Grapefruit Marmalade Recipes

GRAPEFRUIT MARMALADE

Steps:

• Bring a large, covered pot of water to boil with the whole citrus fruit. This Cuisinart pot from Amazon is a decent size for the job. Boil the fruit until they are very tender and soft. Grapefruit take about 2.5 hours. Drain the fruit and let them cool slightly before proceeding.
• Place a cutting board inside a rimmed baking sheet (these Nordic Ware sheet pans from Amazon are great). This is to catch all the citrus juices! Slice each fruit in half to expose the seeds. Remove the seeds if there are any, then quarter each half. Seperate the flesh from the peel so that you can slice the peel thinly and chop the flesh, removing any membranes if they are tough. Transfer the sliced peel, flesh, and juices into a large pot (like this Cuisinart pot from Amazon).
• To the large pot of chopped fruit, add the sugar and the lemon juice. Clip on your thermometer (like this fast-reading digital thermometer from Thermoworks). Bring the mixture to a boil on medium-high, stirring with a wooden spoon or heatproof spatula (grab this spatula from Amazon). When the mixture is boiling, this is when you want to start monitoring the temperature. Boil the mixture, stirring constantly, until it reaches 220°F (104-105 ºC). When the marmalade reaches this temperature, slide the pan off the heat, and let it cool for 2 minutes, then add the vanilla bean paste and give the marmalade a good stir. This is to ensure that your canned marmalade will have an even dispersion of peel/fruit and vanilla bean seeds.
• Divide the mixture between 5 or 6 sterilized jars (I prefer wide-mouth mason jars like these Ball jars on Amazon), leaving a headspace of 1/4 inch. If the 6th jar has a larger headspace, you are just going to have to eat it. Just kidding. Well, except that you can't seal it to store at room temperature, so that will be your jar to enjoy right away, storing it in the fridge. Wipe the rims of all the jars with a lightly moistened paper towel. Top each of the jars with a sterilized lid, and tighten the band until it is finger tight. The Ball canning kit on Amazon is key for this step and the next! Get it on Amazon
• Line a rimmed baking sheet with a large kitchen towel (these Nordic Ware sheet pans from Amazon are great). This will be the "cooling station" for the processed jars. To seal the jars, place them in a large pot, with a towel at the bottom to prevent them from rattling and cracking. Fill the pot with hot water so that the jars are completely immersed. Bring the pot of water to a boil with the lid on and once the boiling point has been reached, boil the jars for 5 minutes. Then take the pan off the heat, and let the jars stand in the pan for another 5 minutes. Finally, carefully remove the jars from the water bath and place them on the towel-lined baking sheet. You will hear a popping sound soon after, a good sign that the vacuum seal is proper. Let the jars cool, untouched, for 24 hours before putting them away.

GRAPEFRUIT MARMALADE

Steps:

• Inspect two 5-ounce jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until marmalade is ready. Wash new, unused lids and rings in warm soapy water.
• Thoroughly wash and dry the grapefruits. Run a zester around 2 grapefruits to produce ribbons of zest. Set aside. Cut away thin strips of peel from the other two grapefruits with a sharp paring knife.
• Peel off all remaining outer white parts of the fruit and discard. Cut the grapefruits into wheels. Remove any seeds.
• Put grapefruit wheels and zest strips into a non-reactive saucepan. Add sugar and stir well to cover fruit. Heat over medium-high heat until bubbling, mixing constantly. Smash the heated fruit until it liquefies. Reduce heat to low and cook over a steady boil, stirring often. Remove and discard any persistent white froth that won't disappear after being stirred. Continue to cook for about 10 minutes until marmalade begins to coat the back of a spoon.
• Add zest ribbons and cook for 5 minutes more. Place a small amount of marmalade on a plate and put it in the freezer. Test the consistency after 3 minutes.
• Remove the marmalade from the heat when the freezer sample meets your desired consistency.
• Pack grapefruit jam into hot, sterilized jars, filling to within 1/4 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 10 minutes.
• Remove the jars from the stockpot and let rest, several inches apart, for 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area.

GRAPEFRUIT MARMALADE

Steps:

• Sterilise the jars you'll be using to store the marmalade.Choose glass jars with an airtight, metal lid and ensure they have been washed in the dishwasher or by hand in hot soapy water then rinsed well.Check that the metal lids do not have rubber inserts. (See Note 9)Preheat the oven to 130 Degrees C (270 F) and place the jars in the oven for 15-20 minutes.
• Place 2 saucers or small plates in the freezer, ready to check for the setting point of your marmalade.Thoroughly wash the grapefruit and lemon. Remove each end of the grapefruit to get rid of excess pith. Remove each end of the lemon. Cut the grapefruit and lemon into quarters length ways. Holding two of the quarters together, slice as thinly as possible and remove any seeds.
• Place the citrus slices in a non-reactive bowl. See Note 4. Add the 6 cups of water, cover the bowl and leave the fruit to stand overnight, up to 24 hours. If your bowl is not large enough to accommodate all the water, add what you can and add the remainder the following day. It's best to make a note of what you have added.The following day, place the fruit and water into a very large, non-reactive saucepan. - See Note 5.
• Over medium-high heat, bring the fruit and water to the boil. Rapidly boil for approximately 15 minutes or until the peel is tender, stirring occasionally with a long-handled wooden spoon - See Note 6.
• Add the sugar and stir well to dissolve it. After dissolving the sugar, return the fruit to the boil, stirring occasionally. Continue to stir until the marmalade reaches setting point - I start to check at about 10 minutes. When the very aggressive bubbles subside to a slower, gentler boil, that's an indication that your marmalade may have reached setting point - See Note 7.Remove from the heat to conduct the wrinkle test. If not set, continue to boil for another 1 minute and then test again.
• To test for setting point, I use the "wrinkle" test. Take one of your saucers from the freezer and pour a small amount of marmalade onto it. Let it cool for a minute then push against the marmalade with the tip of your finger. If the surface wrinkles slightly, it means setting point has been reached.Alternatively, if you are not confident checking this way or are not experienced at making marmalade, you can use the fail-safe method of using a jam/candy thermometer which you clip to the side of your saucepan. When attaching your thermometer, make sure that the base is not touching the bottom of the saucepan. Your marmalade has reached setting point when the temperature reaches 104.5 degree C or 220 degrees F. (Taking it much higher than this will result in the marmalade being overboiled, the pectin being destroyed, and therefore, your marmalade will not set.)At this time, your marmalade will look very liquidy - it can take 24-48 hours to completely cool and set.Please note, this recipe will produce marmalade which has a soft set; it will not be as firm as many commercial varieties which often contain additives.
• Take the mixture off the heat. If there is any scum on the marmalade, add a teaspoon of butter and stir; that should settle the scum.
• Let the marmalade stand for about 10 minutes to allow the fruit to settle. If you bottle it immediately, the fruit will not be evenly distributed but will settle at the top of the jar.
• Remove your jars from the oven and carefully ladle the marmalade into the heated, sterilised jars. The jars should be filled as full as possible to minimise the amount of air between the marmalade and the lid. The marmalade should not touch the lid. Seal tight once filled with marmalade. See Note 8You need to be very careful. Splashing yourself with hot marmalade will result in a very serious burn. I suggest you have clothing with long sleeves and ensure that you do not have children nearby.

GRAPEFRUIT MARMALADE

Steps:

• Peel grapefruit and lemon and cut away 1/2 pith from rind. Cut rind into slivers. Chop the fruit and reserve, along with any juice.
• In an 8-quart non-reactive heavy pot, simmer rind, chopped fruit, reserved juice, water and sugar uncovered on low heat, 10 minutes.
• Pour into a large heatproof glass bowl and let stand, covered, in a cool place overnight.
• Return grapefruit mixture to a pot, and heat on medium-high heat until a sugar thermometer registers 220 degrees F, about 20 to 25 minutes.
• Remove from heat, skim off the foam and ladle into sterilized half-pint canning jars, leaving 1/4-inch space at the top
• Wipe rims, seal jars and process in a boiling water bath for 15 minutes.
• Store in a cool, dark place.

ORANGE-GRAPEFRUIT MARMALADE WITH GINGER

Steps:

• Cut fruit in half, squeeze out juice and pulp, discard seeds. The volume of this should be approximately 4 cups. Remove zest, this should yield approximately 1/2 cup. Transfer juice, pulp and zest to a large glass bowl. Cover and refrigerate for 24 hours. This helps the peel to soften.
• After soaking, put the citrus in a large stockpot. Add 6 cups of water, simmer for 1 1/2 hours. A sample of the peel should feel quite tender if rubbed between fingers. Add sugar and ginger. Bring to a boil, stirring constantly with a wooden spoon. Boil hard for 20 minutes until sugar is dissolved and mixture is thickened. If the mixture foams up, add a pat of butter and the froth will subside.
• Test for jell-point: drop a small amount of hot marmalade on a chilled plate. Return to the freezer for 1 minute. If surface forms a skin, it has reached jelling point, if still syrupy, continue cooking and test again in 5 minutes.
• Remove from heat, stir in pectin. Cool for 15 minutes, spoon into half-pint sterilized jars leaving 1/4-inch headspace and seal.
• ** Recipe Note: Traditionally the citrus seeds and pith are enclosed in a nylon bag and boiled along with the juice/pulp. This releases the natural pectin that is stored in that part of the orange. For time and ease, we eliminated that step and used store-bought fruit pectin. It worked very well.
• ***To sterilize the canning jars, wash the containers in hot, soapy water and rinse. Boil them in a large pot for 10 minutes. Keep the jars in hot water until ready to use to prevent the jars from cracking. Dry with paper towels before filling with marmalade. Once filled, put on lids and collar. Boil again for 10 minutes to seal the jars.

GRAPEFRUIT MARMALADE

Steps:

• Gather the ingredients.
• Wash and dry the grapefruits.
• Use a sharp vegetable peeler or paring knife , remove the brightly colored zest (and only the brightly colored zest) from the grapefruit. Be sure to leave behind any and all of the white pith directly underneath, it is very bitter.
• Chop the resulting zest-bigger pieces for chunkier marmalade, ribbon-like strips for a more spreadable result. Set zest aside.
• Cut the ends off the zested grapefruits.
• Working with one fruit at a time, cut off the thick white pith from around each grapefruit.
• Working over a bowl to catch the juices, hold a fully peeled grapefruit, and use a sharp knife to cut out each section of the membrane holding the sections together.
• Squeeze any juice out of the membrane once you've cut out all the fruit.
• Set the membrane aside, along with any seeds. The pectin in these will help "set" the marmalade later.
• Combine the zest, fruit, juice, 4 cups of water and sugar in a large heavy pot and bring to a boil.
• Meanwhile, lay a double layer of cheesecloth in a medium bowl.
• Put membranes and seeds in the bowl.
• Lift up the corners and tie the cheesecloth into a bag to hold the membranes and seeds.
• Add this " pectin bag " to the pot.
• While the mixture comes to a boil, put a canning kettle full of water on to boil if you're planning to can the marmalade.
• In any case, put a few small plates in the freezer to chill them. When the canning kettle water boils, use it to sterilize the jars and lids.
• Bring marmalade to 220 F and hold it there for 5 minutes. Be patient, this can take quite a while.
• Put a dollop of the mixture on a chilled plate, swirl the plate to spread the mixture a bit, and drag your finger through the mixture. A "set" mixture will hold a clean track behind your finger.
• Remove "pectin bag," squeezing any marmalade in it out and back into the pot before discarding the bag.
• Take marmalade off the heat and let sit 5 minutes.
• Set up clean jars next to the pot.
• Stir marmalade to distribute the zest evenly in the mixture.
• Use a ladle to transfer the marmalade into the jars, leaving 1/2 inch of headspace at the top of each jar.
• Put lids on the jars.
• If you're canning the marmalade, put the jars in the canning kettle and boil for 10 minutes. In any case, let jars cool to room temperature before putting in a cool dry cupboard (if you've hot water processed them) or the fridge (if you didn't hot water process).

PINK GRAPEFRUIT MARMALADE

Steps:

• In a large pot, place the two grapefruit in just enough water to make them float freely.
• Bring to a boil, and let boil for two hours (add water from a kettle if too much boils away and the grapefruit touch the bottom).
• Drain the grapefruit, discard water and let fruit cool (or else you'll burn your hands!).
• Slice the grapefruit as finely as possible, and chop a bit. This is tedious, but not difficult. It doesn't have to be uniform.
• Chuck the grapefruit, sugars and lemon juice back into the pot, and dissolve the sugars on low heat.
• Bring to a boil and let bubble until you reach the jell point, about 15 minutes, give-or-take.
• If you like a smoother consistency, blitz in a blender for a bit until you like what you see.
• Ladle into clean, sterilized jars and process in a hot water bath for ten minutes.

QUICK GRAPEFRUIT MARMALADE

Steps:

• Slice the grapefruit very very thinly with a sharp knife, into flat slices. then cut these into strips, and cut the strips into smaller bits. Keep all the juice that flows out, if it's a juicy grapefruit.
• Bring 6 cups of water to a boil, and then add the grapefruit slices and juice.
• Keep at a low boil, adding the sugar. Continue boiling for quite some time (20-30 minutes), until it begins getting thicker.
• The tricky part is knowing when to stop boiling. If you wait too long, it will become too thick when it cools. The important thing to know is it thickens a bit when cooling, so you have to stop it before it reaches the desired consistency. I put a porcelain dish in the fridge, then pour a little onto the dish - if it congeals a little, then it's ready.
• Before you bottle it, eat it with bread while it's still warm - it's delicious!
• Pour in any clean bottle, and refrigerate.

GRAPEFRUIT MARMALADE WITH VANILLA AND ANISE

Steps:

• Using a sharp knife, remove peel and white pith from 1 grapefruit and thinly slice. Remove peel and white pith from remaining grapefruit and discard (you won't want all of the peel and pith in the marmalade). Slice flesh of both grapefruits into rounds; remove any seeds.
• Combine sliced peel, grapefruit, and star anise in a large saucepan; scrape in seeds from vanilla bean and add pod. Toss to combine; pour in 4 cups water and bring mixture to a boil. Reduce heat and gently simmer until reduced by three-quarters, about 1 1/2 hours. Add sugar, return to a simmer, and cook until mixture is thickened and juices are syrupy (mixture will set up when a small amount is spooned onto a cold plate), 1-1 1/2 hours longer.
• Let marmalade cool slightly, then stir in lemon juice. Spoon into clean jars and let cool.
• Do Ahead
• Marmalade can be made 2 months ahead. Cover and chill.

GRAPEFRUIT-AND-MEYER-LEMON MARMALADE

Steps:

• Remove the grapefruit skin with a vegetable peeler. Cut the peel into 1/8-inch slivers; stop when you have 3/4 cup. Discard the rest. Slice off the ends of the grapefruit and the remaining grapefruit peel and pith. Remove grapefruit segments, reserving membrane. Stop when you have 5 cups of segments.
• Cut the ends off the Meyer lemons, deep enough so you can see the flesh. Leaving the peel on, remove the segments of lemon and reserve the membrane. Cut the segments crosswise into 1/4-inch pieces. Put membranes from the grapefruit and Meyer lemons in a jelly bag and tie closed.
• In a wide and deep pot, combine the grapefruit segments, grapefruit peel, lemon pieces and jelly bag. Add lemon juice and 2 1/2 cups water. Simmer until the grapefruit peel is tender, 25 to 30 minutes. Let cool.
• Preheat the oven to 225 degrees. Working over a bowl in your sink, squeeze the liquid from the jelly bag; keep squeezing and wringing it out until you extract 1/3 to 1/2 cup of pectin. Add pectin and sugar to the pot. Place over high heat and boil, stirring now and then, until marmalade is between 222 and 225 degrees and passes the plate test. (Spoon a little onto a plate and put in the fridge for 3 minutes. If it thickens like jam, it is done.)
• Meanwhile, put 6 sterilized 8-ounce canning jars and lids on a baking sheet and place in the oven. When jam is done, remove jars from the oven. Ladle jam into the jars, filling them as high as possible. Wipe the rims. Fasten the lid tightly. Let cool. If you don't get a vacuum seal, refrigerate the jam.
