Certo Strawberry Rhubarb Jam Recipes

Steps:

• Rinse clean plastic containers and lids with boiling water. Dry thoroughly.
• Measure crushed strawberries and finely chopped rhubarb into large bowl. Stir in sugar. Let stand 10 minutes, stirring occasionally.
• Mix pectin and lemon juice in small bowl. Add to fruit mixture; stir 3 minutes or until sugar is dissolved and no longer grainy. (A few sugar crystals will remain.)
• Fill all containers to within 1/2 inch of tops. Wipe off top edges of containers; immediately cover with lids. Let stand at room temperature 24 hours. Jam is now ready to use. Store in refrigerator up to 3 weeks or freeze extra containers up to 1 year. Thaw in refrigerator before using.

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:

• 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:

• 1. RINSE clean plastic containers and lids with boiling water. Dry thoroughly.
• 2. MEASURE crushed strawberries and finely chopped rhubarb into large bowl. Stir in sugar. Let stand 10 minutes, stirring occasionally.
• 3. MIX pectin and lemon juice in small bowl. Add to fruit mixture; stir 3 minutes or until sugar is dissolved and no longer grainy. (A few sugar crystals will remain.)
• 4. FILL all containers to within 1/2 inch of tops. Wipe off top edges of containers; immediately cover with lids. Let stand at room temperature 24 hours. Jam is now ready to use. Store in refrigerator up to 3 weeks or freeze extra containers up to 1 year. Thaw in refrigerator before using.

Steps:

• Rinse clean plastic containers and lids with boiling water. Dry thoroughly.
• Stem and crush strawberries thoroughly, one layer at a time. Measure exactly 2 cups prepared fruit into large bowl. Stir in sugar. Let stand 10 min., stirring occasionally.
• Mix pectin and lemon juice in small bowl. Add to strawberry mixture; stir 3 min. or until sugar is dissolved and no longer grainy. (A few sugar crystals may remain.)
• Fill all containers immediately to within 1/2 inch of tops. Wipe off top edges of containers; immediately cover with lids. Let stand at room temperature 24 hours. Jam is now ready to use. Refrigerate up to 3 weeks or freeze up to 1 year. Thaw in refrigerator.

Steps:

• Prepare your jars and lids for canning. This recipe makes approximately 8 cups.
• Remove the stems from the strawberries, and crush to 2 1/4 cups. You can crush with a potato masher, food processer, or my favorite way, by hand.
• Chop rhubarb (you'll need it to measure 1 3/4 cups), place in saucepan with 1/2 cup water, bring to boil and boil about 2 minutes, or until rhubarb is soft.
• In a large (6- or 8-quart) pot, combine the strawberries, drained rhubarb, sugar, and butter if using and bring to a full rolling boil over high heat.
• Add the pectin and bring back to a boil. Boil for one minute and then remove from the heat.
• Skim off any foam (if you used the butter, there may not be any foam) and pour into your prepared jars leaving 1/8 inch headspace.
• Wipe jar rims and threads, cover with two piece lids, screw bands on and boil in a canner for 10 minutes.
• Remove jars from canner and allow to sit overnight. Check the seal, if any jars did not seal, place in the fridge and use immediately. Store properly sealed jars up to one year in a cool dry place.

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.
• Stem and crush strawberries thoroughly, one layer at a time. Measure exactly 4 cups crushed strawberries into 6- or 8-quart saucepot.
• Add sugar; stir. Add butter to reduce foaming. Bring to full rolling boil (a boil that doesn't stop bubbling when stirred) on high heat, stirring constantly. Stir in pectin. Return to full rolling boil and boil exactly 1 minute, 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 2-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 minutes. Remove jars and place upright on towel to cool completely. After jars cool, check seals by pressing middle of lid with finger. (If lid springs back, lid is 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:

• Mix rhubarb and sugar in a large heavy pot and let stand for 2 hours; stir in lemon juice and strawberries. Bring the mixture to a boil, stirring to dissolve sugar. Set heat to medium-high and cook jam at a full rolling boil until thickened, stirring often to prevent scorching, 20 to 25 minutes. A candy thermometer inserted into the middle of the jam, not touching the pot, should read 220 degrees F (105 degrees C).
• Remove jam from heat and stir for 2 to 3 more minutes; skim off any foam.
• Sterilize the jars and lids in boiling water for at least 5 minutes. Pack the jam into the 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.
