Certo Green Tomato Jam Recipes

TOMATO JAM

Steps:

• Toss tomatoes, sugar and salt together in a large, heavy bottomed pot. Let sit at least 15 minutes or up to overnight, tossing to coat periodically to dissolve the sugar. (This helps coax the juices out of the tomatoes.)
• Place a small plate in the refrigerator to chill. (You'll use this later.)
• Add the vinegar to the tomatoes, and bring to a strong simmer over medium heat until the skins burst and the juices start to boil, about 10 minutes. Add in any of the optional ingredients (see note), if using.
• Increase the heat to medium-high, and cook the jam. Using a wooden spoon or spatula, stir the jam, occasionally at first and more frequently as the juices thicken. Do this until most of the liquid has evaporated and the tomatoes have begun to break down, and the mixture resembles a very thick, shiny tomato sauce, 35 to 45 minutes. This is the stage at which it's most important to stir constantly along the bottom of the pot to prevent scorching and sticking. (Sugar is heavier than water and will concentrate at the bottom of the pot, increasing the chance that the fruit will burn.) How much the tomatoes break down will depend on their type and how ripe they are: For example, firm green tomatoes are likely to remain chunky, while ripe red tomatoes will break down almost entirely.
• To test for thickness, spoon a bit of jam onto the chilled plate, return it to the refrigerator and chill for 2 minutes. Drag your finger through it: It should hold its shape on either side without appearing watery or runny. If it's not there yet, continue to cook a few minutes more.
• Remove from heat and discard the chiles de árbol, if using. Divide the jam between jars, leaving 1/4 inch of head space, and seal immediately. Can the jams (see our How to Make Jam guide for more instruction), or store in the refrigerator, using them up within a couple of weeks.

• Gather the ingredients.
• Wash green tomatoes and pat dry. Remove core. Chop tomatoes into small pieces, removing seeds. Place tomato pieces in a large, nonreactive pot with a heavy bottom.
• Zest lemon and keep zest refrigerated in a small bowl with a small amount of lemon juice to keep it hydrated. Add sugar and juice of half the lemon to tomatoes. Toss and leave in refrigerator, covered, to macerate overnight.
• By the next morning, tomatoes should have given off a fair amount of liquid. Place pot over medium-high heat, and bring to a boil, stirring occasionally to avoid scorching. Lower heat to a low boil, and cook for about an hour, again stirring occasionally.
• When mixture pulls away from pan when stirred, remove from heat. Add lemon zest. With an immersion blender , purée mixture thoroughly. Alternatively, use a regular blender , working in batches.
• Pour jam into clean jars , and allow to cool to room temperature. Seal and store in refrigerator for up to three weeks, or in freezer for up to three months.

GREEN TOMATO MARMALADE

Steps:

• Using a vegetable peeler, remove the top layer of rind from the oranges and lemon, being careful not to remove any of the bitter, white pith. Sliver the rind. Set aside while you segment the oranges and lemons.
• In a small saucepan, boil the slivered rind in 1 cup water for 5 minutes. Drain and rinse.
• Core the green tomatoes, then cut them into small pieces. Make sure these pieces are the size you want in your jam.
• Place the drained citrus rind, citrus pulp, green tomatoes, sugar, and ginger in a large pot. Bring to a boil and boil uncovered until the jam sets. The timing will vary greatly depending on how green your tomatoes are and how big you cut them. Mine took 2 hours.
• Meanwhile, sterilze the preserving jars and prepare a water bath for processing. Click here for a step-by-step overview if you are new to preserving or need a refresher.
• When the mixture reaches the setting point, fill the prepared jars with hot marmalade, leaving a 1/4 inch of headspace. Wipe the rims clean. Place lids on the jars and screw on the band until finger-tip tight. Process the jars in a boiling water bath for 10 minutes.
• Once you remove the jars from the bath, allow to cool undisturbed for 24 hours. Check to ensure jars have sealed.

Steps:

• Rough chop the tomatoes and place into a non-reactive sauce pan. Add salt, sugar and lemon juice to the pan and place pan over medium heat. Bring the mixture to a boil, stirring all the while to help break down the tomatoes and fully mix the ingredients. Once at a boil, reduce heat to medium low, allowing the mixture to simmer for 35-40 minutes, stirring regularly to keep the mixture from scorching. With about 5 minutes left on the simmer, add in vanilla and lemon zest. Stir until fully incorporated. Pour the hot mixture into a strainer and remove the seeds and skin. Place the strained mixture into a mason jar and allow to cool. Will keep in the fridge for about 1 week.

Lower rack into canner. (Water must cover jars by 1 to 2 inches. Add boiling water, if necessary.) Cover; bring water to gentle boil. Process 10 min. Remove jars and place upright on a towel to cool completely. After jars cool, check seals by pressing middle of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)
