Small Batch Grapefruit Jam Recipes

EASY SMALL BATCH REFRIGERATOR JAM (BLUEBERRY OR STRAWBERRY)

Steps:

• Combine the blueberries (or strawberries) and the sugar in a medium saucepan. Mash berries slightly with a potato masher or the bottom of a fork. Bring mixture to a boil over medium-high heat, stirring occasionally.
• As soon as the berries begin to boil, begin to stir.
• Continue to cook and stir occasionally until jam begins to thicken. During the last few minutes of cook time, stir vigorously so that the mixture doesn't stick to the bottom of the pan.When the mixture reaches a gel consistency, remove pan from the heat.
• Pour into a clean glass jar.

SMALL-BATCH GRAPEFRUIT JAM

Steps:

• Place a saucer in your freezer for the wrinkle test, before you begin.
• Prepare the grapefruit: Cut off the top and bottom of a grapefruit and sit flat on a cutting board. Using a sharp knife and starting from the top, cut off the peel along the sides, working your way around until it is all removed. Turn grapefruit over and remove any remaining peel. You should not have any peel or pith left on the fruit.
• While holding the grapefruit over a large bowl, cut between the membranes of the fruit to remove a grapefruit slice. Continue to remove all the slices and give it a gentle squeeze to remove a bit of the juice. Repeat with all the grapefruits.
• Cook the jam: Add the grapefruit and juice to a large, non-reactive, heavy bottomed pot. Add the sugar and stir well to combine. Bring the mixture to a boil, over high heat, stirring regularly until the sugar dissolves. Once the mixture reaches a steady rolling boil, allow to continue boiling, testing regularly with the "wrinkle test", until it's set. It will take about 10-15 minutes. You can also monitor using a thermometer. The jam will set somewhere around 220° F., but the exact temperature will vary a bit, depending on your altitude, so verify setting with the wrinkle test.
• Ladle jam into small jars. Cover and refrigerate to use in the short term. Jam will keep several months in the fridge. (*As it is not properly "canned", do not store at room temperature).

SMALL BATCH GRAPEFRUIT JAM

Steps:

• Start by supreming the grapefruit. Do this by cutting the top and bottom off. Then, working from north pole to south, cut the rind off the fruit (you want to expose the interior surface of the fruit). When rind is entirely removed, use the knife to separate the fruit from the membrane of the fruit.
• Collect the naked fruit sections and their juice in a large bowl. Set any seeds you find aside. Bundle them up in a length of cheesecloth. They'll give the jam an extra hit of pectin.
• Once all the fruit is supremed, pour it into a large, non-reactive pot and add the sugar and the cheesecloth bundle containing the seeds. Stir until the sugar begins to dissolve.
• Turn the heat to high and bring the fruit mixture to a boil. Cook at a bubble, stirring regularly, until the jam reaches 220 degrees and passes the plate/sauce/wrinkle test (remove the pot from the heat source while you're testing to prevent scorching).
• When the jam passes these set tests, pour into prepared jars. Apply lids and rings and process in a boiling water bath for ten minutes.
• When time is up, remove jars from canner and let them cool on a folded kitchen towel. When jars are cool to the touch, remove rings and test seals. Store sealed jars in a cool, dark place. Any unsealed jars should be refrigerated and used first.
