Preserved Tomato PurÉe Recipes

PRESERVED TOMATO PURéE

Steps:

• Peel, core and roughly chop tomatoes. Put in a large nonreactive pot, cover and simmer 10 minutes. Purée through medium disc of a food mill to remove skins and most seeds.
• Put a rack in a large stockpot or line pot with a folded kitchen towel, then fill with water and bring to a boil. Add quart or pint jars and boil 10 minutes. Jars may be left in warm water until ready to fill. Alternatively, sterilize jars by running them through a dishwasher cycle, keeping them warm in the machine.
• Place canning rings in small saucepan, cover with water and bring to a boil. Turn off heat and add flat lids to soften rubber gaskets. Rings and lids may be left in water until jars are filled.
• Bring purée to a boil, then down to a sturdy simmer and cook to reduce by one third, about 30 minutes. Ladle hot purée into warm jars, leaving a little more than 1/2 inch head space to accommodate lemon juice. If using citric acid, fill to 1/2 inch head space.
• Into every quart jar, add 2 tablespoons lemon juice or 1/2 teaspoon citric acid. For pints, use one tablespoon lemon juice or 1/4 teaspoon citric acid. If using salt, add 1 teaspoon to each quart or 1/2 teaspoon to each pint jar.
• Wipe jar rims clean with a damp towel. Place lids on jars, screw on rings and lower jars upright into pot of boiling water. Return to a full boil and process for 45 minutes for quarts or 35 minutes for pints. If there are mixed sizes, process for the longer time. Transfer jars to a folded towel and let cool for 12 hours. Jars will ping as they seal.
• Once cool, test the seals by removing rings and lifting jars by their flat lids. If a lid releases, the seal has not formed. Unsealed jars should be refrigerated and used within one week or reprocessed. Rings and jars may be reused, but a new flat lid must be used each time.

PRESERVED ROASTED TOMATO PURéE

Steps:

• Heat oven to 325 degrees. Core and halve tomatoes and scoop out seeds and gel. Pile tomatoes into a large roasting pan, or on 2 sheet pans, cut side up. Do not add oil.
• Roast tomatoes for 2 hours. Thoroughly purée tomatoes using a blender or immersion blender. It should be smooth and velvety, with no pieces.
• Put a rack in a large stockpot or line pot with a folded kitchen towel, then fill pot with water and bring to a boil. Add pint jars and boil for 10 minutes. Jars may be left in warm water until ready to fill. Alternatively, sterilize jars by running them through a dishwasher cycle, keeping them warm in the machine.
• Place canning rings in a small saucepan, cover with water and bring to a boil. Turn off heat and add flat lids to soften their rubber gaskets. Rings and lids may be left in water until jars are filled.
• In a nonreactive pan, bring purée to a brisk boil for 5 minutes. Ladle hot tomato purée into warm jars leaving 1/2 inch head space, plus room to accommodate lemon juice. If using citric acid, fill to 1/2 inch head space.
• Into every pint jar, add one tablespoon lemon juice or 1/4 teaspoon citric acid. If using salt, add 1/2 teaspoon to each pint jar.
• Wipe jar rims clean with a damp towel. Place lids on jars, screw on rings and lower jars upright into boiling water. Return to a full boil and process for 35 minutes. Transfer jars to a folded towel and let cool for 12 hours. Jars will ping as they seal. Once cool, test seals by removing rings and lifting jars by flat lids. If a lid releases, the seal has not formed. Unsealed jars should be refrigerated and used within three days or reprocessed. Rings and jars may be reused, but a new flat lid must be used each time.

TOMATO PURéE, OR, AS WE CALL IT, THE PRESERVE

Steps:

• Bring a large pot of water to the boil on high heath.
• Throw into the pot the San Marzano tomatoes previously washed (you can do this in more batches, according to the quantity of the tomatoes and to the size of the pot you chose).
• Let the water resume the boil and after 2 - 3 minutes remove the tomatoes and put them in a clean large cotton cloth.
• Prick the tomatoes with a fork and then close the cloth to form a bag, as pictured above.
• Hang the bag so that it can drain all the water, squeezing it often with your hands.
• After about 2 to 3 hours, when the tomatoes have lost all the water, pass them through a vegetable mill using the finest sieve.
• Collect the tomato purée in a bowl, then pour it into sterilized bottles or jars, adding a few leaves of basil.

TOMATO PUREE

Steps:

• Gather the ingredients.
• Starting with clean, dry tomatoes, halve smaller tomatoes and roughly chop larger tomatoes. The tomatoes are going to be pureed, so they don't need to be chopped evenly; cutting allows the tomatoes to release their liquid and cook down faster.
• Put all the tomatoes in a pot.
• Over medium-high heat, bring them to a boil. As the temperature in the pot increases, the tomatoes will release some of their liquid, providing their own liquid in which to cook. Reduce the heat to maintain a steady and active simmer (gentle small bubbles should pop up here and there). Cook, stirring frequently until the tomatoes start to break down, for 10 to 15 minutes.
• Let the mixture cool for at least 5 minutes. Run the tomato mixture through a food mill or whirl quickly in a blender or food processor.
• Strain the puree through a fine-mesh sieve to remove the seeds and bits of skin; this also makes for a smooth puree.
• If the tomato puree is thin and looks watery, you can return the puree to the pot, bring it to a boil, and then reduce the heat to maintain a simmer. Cook until it reduces to the texture you want, stirring often. Taste it along the way-you want a nice, bright tomato flavor along with a smooth and slightly thick texture.
• Transfer the puree to sealable container(s), leaving an inch of headroom, and chill or freeze until ready to use.
• Bring a large canning kettle full of water to a boil.
• Sterilize the pint jars by boiling them for 10 minutes.
• Allow the jars to air dry.
• Soften the lids by simmering them for a few minutes.
• Put 1/4 teaspoon citric acid or 1 tablespoon lemon juice in each pint jar.
• Return the puree to the stove and bring back to a simmer.
• Fill each jar with the hot tomato puree, leaving about 1/2-inch headspace at the top of each jar.
• Set the lids on the jars and secure them with the rings.
• Lower the jars into the canning kettle and boil for 40 minutes. The jars should be covered by at least 1-inch of water.
• Remove the jars and let cool.

HOMEMADE TOMATO PUREE

Steps:

• Wash tomatoes, cut in half, and remove cores. Roughly chop tomatoes and place into a large pot with salt.
• Bring tomatoes to a boil over medium-high heat. Reduce heat to medium and continue to cook, stirring occasionally, until tomatoes are soft and reduced down, about 20 minutes. Remove from the heat and let cool, about 30 minutes.
• Place tomatoes in a blender and puree until smooth, about 30 seconds. Strain tomatoes through a fine mesh strainer, pushing the mixture through with the back of a spoon to remove bits of skin and seeds.
• Ladle into 2 clean pint-sized jars and store in the refrigerator for up to 1 week. If you prefer a thicker puree, return to the pot and simmer to desired consistency, then cool and place in jars.

OVEN-ROASTED TOMATO PASTE OR PUREE

Steps:

• Peel tomatoes. The easiest way to do this is to drop them into a container of boiling-hot water, leave for 1 minute, then drop them into a container of ice-water - the skin slips right off). Halve them and put into a baking pan large enough to hold them in one layer.
• Dribble with olive oil (the amount is arbitrary - I imagine that's about what I use), sprinkle with minced garlic, generously season with salt, pepper, basil and oregano. Give everything a stir to distribute.
• Pop into 350F oven and roast for about 3 hours (this is approximate - it all depends on how thick you want your puree or paste).
• When they're done, I like to mash the tomatoes into a paste because I like a more rustic texture. If you want smoother, use a processor.
• I keep the puree/paste in a tupperware container, in the refrigerator, covered by a thin film of olive oil to prevent oxidization. I dig into it almost daily to provide a burst of flavour into many, many dishes like soups, stews, sauces, gravies, omelettes, etc.
• This freezes well, too.
