Four Berry Jam Recipes

Steps:

• Crush berries in a Dutch oven. Stir in pectin; bring to a full rolling boil over high heat, stirring constantly. Stir in sugar; return to a full rolling boil. Boil for 1 minute, stirring constantly. , Remove from the heat; skim off any foam. Carefully ladle hot mixture into hot half-pint jars, leaving 1/4-in. headspace. Remove air bubbles, wipe rims and adjust lids. Process for 10 minutes in a boiling-water canner.

Steps:

• Toss berries and sugar together in a large, heavy-bottomed pot. Let sit for at least 15 minutes and up to overnight, periodically tossing to coat and to dissolve the sugar. (This will help coax the juices out of the fruit.)
• Place a small plate in the refrigerator to chill. (You'll use this later.)
• Bring the fruit to a strong simmer over medium heat until the berries burst and the juices start to boil, about 15 minutes. If using a vanilla bean as an add-in, put it in the pot at this point.
• Increase the heat to medium-high. Cook the jam, at first stirring occasionally with a wooden spoon or spatula, then more frequently as the juices thicken. Cook until most of the liquid has evaporated and the fruit has begun to break down, 40 to 50 minutes. How much it breaks down will depend on its type and ripeness: For example, strawberries are likely to retain more of their shape, while raspberries will break down almost entirely.
• As the jam cooks, the liquid will reduce, the sugars thicken and the natural pectins activate. You'll notice the liquid go from a rapid, rolling boil with smaller bubbles to a slow, thick, tarlike boil with larger bubbles: 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 there, increasing the chance that the fruit will burn.) It's also the stage at which splattering may occur, so take care in stirring.
• Once the jam reaches a slow, thick boil, add lemon juice and continue to cook, stirring constantly until the jam returns to its earlier consistency, about another 5 minutes. To test the consistency, 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, cook a few minutes more. (Note: Some fruit, like strawberries, contain more water and less natural pectin than say, a raspberry. This means the jam will never be quite as thick or gelled, but it will still be delicious).
• Remove from heat, and incorporate any of the add-ins listed (see notes). Pick out vanilla bean if you added it earlier. Divide jam between several 8-ounce canning jars, leaving 1/4-inch 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 within a couple of weeks.

Steps:

• Prepare your jars in advance--sterilize them and keep the jars, lids, and rings warm while preparing the jam. Have all tools ready and handy (ladle, towel, wet cloth, canning jar funnel, etc).
• Crush berries in a large, non-reactive (such as stainless steel) saucepot. Stir in pectin until dissolved.
• Bring to a full, rolling boil over high heat, stirring constantly to avoid scorching (reduce heat to medium-high if needed).
• Stir in sugar. Return to a full, rolling boil and boil for exactly 1 minute (starting from when you can no longer stir the bubbles down).
• Remove from heat and quickly skim off any foam. You must move quickly at this point to prevent the jam from cooling off too much.
• Quickly ladle hot jam into hot, sterilized jars, leaving 1/4 inch headspace.
• Wipe rims with a clean, warm, damp cloth to ensure a good seal. Place lids on jars and screw rings on snugly but not too tight. Flip jars upside down. Let stand upside down for 5 minutes, then turn right-side up again. Let sit for one hour.
• After one hour, check seals. If any lids are still popped up (there is a bump in the center of the lid that should be down if the jar is sealed, and up if not), then refrigerate and use immediately, or process in a hot water bath for 10 minutes.
• Store jars in a cool, dark place until ready to use; use within 1 year.

Steps:

• Combine fruit, sugar, and lemon juice in large bowl. Let stand at room temperature 2 hours, stirring occasionally.
• Put 2 saucers in freezer.
• In bottom of heavy large stockpot at least 3 inches deeper than height of jars, place metal rack or extra screw bands from canning jars to protect jars from direct heat. Fill pot with water, cover, and bring water to boil. Reduce heat to low. Wash jars, lids, and screw bands in hot soapy water; rinse well. Set screw bands on clean towel to dry. Place lids in small saucepan; cover with cold water and bring to simmer; turn off heat. Fill jars with very hot water.
• Transfer fruit mixture to large saucepan and bring to boil over medium-high heat, stirring occasionally. Mash to thick puree with potato masher. Reduce heat to medium and boil gently until mixture begins to thicken, stirring often, about 18 minutes.
• Remove saucepan from heat to test jam for gelling point. Drop 1 teaspoonful jam on chilled saucer and return to freezer 1 minute. Remove saucer and push edge of jam with fingertip. If jam has properly gelled, surface will gently wrinkle. If not, return saucepan to heat and cook jam a few minutes longer; repeat test.
• Drain hot water from jars and shake out excess water. Place jars on cutting board. Ladle hot jam into each jar, leaving 3/4-inch space at top. Slide flat plastic spatula between jam and jar to eliminate air bubbles. Clean rim of each jar with damp cloth. Using tongs, lift hot lids from saucepan, 1 at a time, shake dry, and place atop jars. Seal each with screw band, twisting to close but not too tightly. Return filled jars to pot of hot water.
• Add water to pot, if necessary, to cover jars by at least 1 inch. Cover pot and bring to boil; reduce heat and boil gently 10 minutes. Turn off heat. Wait 5 minutes; use tongs to remove jars without tilting. Place upright on towel; cool completely at room temperature. Jam will thicken as it cools.
• Check lids for seal by pressing each lightly. Lids of sealed jars will be concave and show no movement when pressed.

Steps:

• Combine the berries and lemon juice in a stockpot; crush fruit slightly. Stir in pectin. Bring to a full rolling boil over high heat, stirring constantly. Stir in sugar; return to a full rolling boil. Boil 1 minute, stirring constantly. , Remove from the heat; skim off any foam. Carefully ladle hot mixture into hot pint jars, leaving 1/4-in. headspace. Remove air bubbles; wipe rims and adjust lids. Process for 10 minutes in a boiling-water canner.
