Ball Blue Book Strawberry Rhubarb Jam Recipes

Steps:

• Toss the rhubarb, strawberries, sugar, lemon zest and juice and 3/4 teaspoon salt in a large saucepan to combine, then mash slightly to release some of the berry juice. Set aside for 10 minutes to allow the mixture to macerate and the sugar to dissolve. Meanwhile, place a small plate in the freezer to chill; this will be used to test the doneness of the jam.
• Place the saucepan over medium-high heat. (See Cook's Note for flavor additions.) Bring the mixture to a boil and then reduce the heat to medium low, stirring frequently. Continue to cook until the jam becomes thick and syrupy, about 1 1/2 hours. To test doneness, place a small amount of the jam onto the chilled plate and freeze for 2 minutes. Drag your finger or spoon through the jam. If the jam holds its shape and thickness, remove from the heat. If it's runny, continue to cook and test again in 5-minute increments. Once the jam has reached the right consistency, transfer to jars and cool completely before storing, covered tightly. Jam will keep in the refrigerator for up to 6 months.

Steps:

• 1. Sterilize 1/2 pint jars and lids.
• 2. Combine strawberries, rhubarb, lemon juice and pectin in a large saucepan (it will foam up, so use a large pan.) Bring to a boil.
• 3. Add sugar, stir to dissolve. Return to a boil and boil hard for 1 minute, stirring all the time.
• 4. Ladle hot jam into jars leaving 1/4" space at the top. Wipe the rim of the jars with a damp paper towel to remove any jam. Adjust lids and rings (not over tight.)
• 5. Process 10 minutes in a water bath canner. *A very large stockpot with a tight lid will work just fine if you don't have a canner.

Steps:

• Place rhubarb, strawberries, lemon juice, fruit pectin, and butter into a large kettle over medium heat. (Butter is optional but helps keep jam from getting too foamy). Stir the fruit mixture to help the juice start to form, and add sugar, about 1 cup at a time, stirring constantly until sugar is dissolved and the juice is starting to simmer. Turn up heat to medium-high, bring the mixture to a full rolling boil, and cook and stir for 1 minute. Skim off any foam that forms.
• Sterilize the jars and lids in boiling water for at least 5 minutes. With a jelly funnel and a soup ladle, pack the jam into the hot, sterilized jars, filling the jars to within 1/4 inch of the top. Run a knife or a thin spatula around the insides of the jars after they have been filled to remove any air bubbles. Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with lids, and screw on rings.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil over high heat, then carefully lower the jars into the pot using a holder. Leave a 2 inch space between the jars. Pour in more boiling water if necessary until the water level is at least 1 inch above the tops of the jars. Bring the water to a full boil, cover the pot, and process for 5 minutes.
• Remove the jars from the stockpot and place onto a cloth-covered or wood surface, several inches apart, until cool. To help the jam set, don't move or touch the jars until cooled. Once cool, press the top of each lid with a finger, ensuring that the seal is tight (lid does not move up or down at all). Store in a cool, dark area.

Steps:

• Bring boiling-water canner, half full with water, to simmer. Wash jars and screw bands in hot soapy water; rinse with warm water. Pour boiling water over flat lids in saucepan off the heat. Let stand in hot water until ready to use. Drain well before filling.
• Remove stems from strawberries; discard stems. Crush strawberries thoroughly. Measure exactly 2-1/4 cups prepared strawberries into 8-qt. stockpot. Finely chop unpeeled rhubarb. Place in medium saucepan. Stir in water. Bring to boil. Reduce heat to medium-low; cover. Simmer 2 min. or until rhubarb is tender. Measure exactly 1-3/4 cups prepared rhubarb into saucepot with strawberries; mix well.
• Stir pectin into prepared fruit mixture in stockpot. Add butter to reduce foaming. Bring mixture to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in sugar. Return to full rolling boil and boil exactly 1 min., stirring constantly. Remove from heat. Skim off any foam with metal spoon.
• Ladle immediately into prepared jars, filling to within 1/4 inch of tops. Wipe jar rims and threads. Cover with two-piece lids. Screw bands tightly. Place jars on elevated rack in canner. 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 middles of lids with finger. (If lids spring back, lids are not sealed and refrigeration is necessary.)

Steps:

• In a Dutch oven, combine strawberries, rhubarb and lemon juice; stir in pectin. Bring to a full rolling boil, stirring constantly. Stir in sugar; return to a full rolling boil. Boil and stir 1 minute. , Remove from heat; skim off foam. Ladle hot mixture into 6 hot sterilized pint jars, leaving 1/4-in. headspace. Remove air bubbles and adjust headspace, if necessary, by adding hot mixture. Wipe rims. Center lids on jars; screw on bands until fingertip tight., Place jars into canner with simmering water, ensuring that they are completely covered with water. Bring to a boil; process for 5 minutes. Remove jars and cool.

Steps:

• Slice the strawberries and rhubarb if using fresh fruit. Set aside.
• Mash and cook raspberries till they're soft and juicy. Strain through several layers of cheesecloth. Twist into a ball and SQUEEZE to get all the juice. Scrape the outside to get all the pulp. You don't need clear juice since this is jam. Skip this step if you don't mind the seeds.
• Put the strawberries, rhubarb, raspberries or strained juice and sugar in at least a 5 qt pan. Add water if needed to prevent scorching.
• Bring to a gentle simmer and cook to 220F on a candy/jelly thermometer or test for jelly by putting a couple of tablespoons on a saucer and letting it cool. Stir frequently.
• Ladle into hot canning jars. Cover with hot lids and bands.
• Process in a water bath for 20 minutes.
• Remove and allow to cool. Listen for the "pops".
