Marthas Strawberry Jam Recipes

Steps:

• In a wide bowl, crush strawberries in batches until you have 4 cups of mashed berry. In a heavy bottomed saucepan, mix together the strawberries, sugar, and lemon juice. Stir over low heat until the sugar is dissolved. Increase heat to high, and bring the mixture to a full rolling boil. Boil, stirring often, until the mixture reaches 220 degrees F (105 degrees C). Transfer to hot sterile jars, leaving 1/4 to 1/2 inch headspace, and seal. Process in a water bath. If the jam is going to be eaten right away, don't bother with processing, and just refrigerate.

Steps:

• Heat strawberries and sugar in a medium saucepan over medium heat. Cook, stirring, until bubbling and thickened, 10 to 15 minutes. Transfer to a glass jar and let cool completely.

Steps:

• Bring rhubarb, sugar, and 1/4 teaspoon salt to a boil in a large pot, stirring often. Cook, stirring often, until bubbles slow, foam subsides, fruit rises to the top, and jam sticks to a wooden or metal spoon when lifted from mixture, about 10 minutes. Stir in lemon juice to taste. Let cool for 1 hour. Refrigerate overnight.

Steps:

• Put a small plate in the freezer. Place berries in a nonreactive 10-quart stockpot set over medium-high heat. Using a wooden spoon, mix in 1/4 cup sugar with berries. Cook, stirring, until berries are juicy, 5 to 6 minutes. Stir in a third of remaining sugar until dissolved. Repeat until all the sugar has been added and dissolved, about 7 minutes total.
• Bring mixture to a full boil; cook, stirring, 10 minutes. Continue boiling; use a stainless-steel spoon to remove foam from surface. Boil until most of the liquid is absorbed, mixture thickens, and temperature registers 220 degrees on a candy thermometer, about 30 minutes.
• Perform a gel test: Place a spoonful of jam on chilled plate, and return to freezer. Wait 1 to 2 minutes; remove plate from freezer, and gently press jam with fingertip; it should wrinkle slightly.
• After jam passes the gel test, remove from heat. Pour warm jam into jars; seal, label, and refrigerate up to 4 months.

Steps:

• Combine the sugar, lemon zest, and lemon juice in a small saucepan and cook over very low heat for 10 minutes, until the sugar is dissolved. Add the strawberries and continue to cook over very low heat for 20 minutes, until the strawberries release some of their juices and the mixture boils slowly. Cook until a small amount of the juice gels on a very cold plate. (I keep one in the freezer.) Pour carefully into 2 pint canning jars and either seal or keep refrigerated. Use immediately, or follow proper canning guidelines below.
• Sterilizing Tips:
• Jars should be made from glass and free of any chips or cracks. Preserving or canning jars are topped with a glass, plastic, or metal lid, which has a rubber seal. Two piece lids are best for canning, as they vacuum seal when processed.
• To sterilize jars, before filling with jams, pickles, or preserves, wash jars and lids with hot, soapy water. Rinse well and arrange jars and lids open sides up, without touching, on a tray. Leave in a preheated 175 degree F oven for 25 minutes. Or, boil the jars and lids in a large saucepan, covered with water, for 15 minutes.
• Use tongs when handling the hot sterilized jars, to move them from either boiling water or the oven. Be sure the tongs are sterilized too, by dipping the ends in boiling water for a few minutes.
• As a rule, hot preserves go into hot jars and cold preserves go into cold jars. All items used in the process of making jams, jellies, and preserves must be clean. This includes any towels used, and especially your hands.
• After the jars are sterilized, you can preserve the food. It is important to follow any canning and processing instructions included in the recipe and refer to USDA guidelines about the sterilization of canned products.

Steps:

• In a food processor, process strawberries until coarsely chopped. Transfer to a large skillet and stir in sugar and lemon juice. Cook over medium-high, stirring frequently, until jam is thickened and bubbles completely cover surface, 9 to 10 minutes. Transfer jam to a jar and let cool to room temperature. (To store, seal jar and refrigerate, up to 10 days).

Steps:

• Place the mason jars in a large hot water bath canner (or pot). Cover with water and bring to a simmer. Simmer the center lids in separate saucepan full of water.
• Place the mashed strawberries and lemon juice in a separate pot. Stir in the pectin until dissolved. Bring the strawberries to a strong boil.
• Add the sugar (measure beforehand so you can add it all at once), and then return the mixture to a full (violent) boil that can't be stirred down. Boil hard for 1 minute 15 seconds. Skim foam off the top.
• Remove one jar at a time from the simmering water. Pour water back into the pot. Using a wide-mouth funnel, fill each jar with jam, being careful to keep the liquid/fruit ratio consistent. Fill the jars so that they have 1/4-inch of space at the top. Run a knife down the side of the jar to get rid of air bubbles. Wipe the rim of the jar with a wet cloth to remove any residue or stickiness.
• Remove the center lid from the simmering water and position it on top. Put screw bands on jars, but do not over tighten! Repeat with all the jars, and then place the jars on a canning rack and lower into the water. Place the lid on the canner, and then bring the water to a full boil. Boil hard for 10 to 12 minutes.
• Turn off the heat and allow the jars to remain in the hot water for an addition 5 minutes. Remove the jars from the water using a jar lifter, and allow them to sit undisturbed for 24 hours.
• After 24 hours, remove the screw bands and check the seal of the jars. The center lids should have no give whatsoever. If any seals are compromised, store those jars in the fridge. Otherwise, fill your pantry with your newly canned goodness.

Steps:

• Make the crust: Preheat oven to 350 degrees. In a food processor, blend flour, butter, 1/3 cup sugar, and salt until moist crumbs form (this may take up to 1 minute). Transfer dough to a 9-inch round tart pan with a removable bottom.
• With floured fingers, press dough evenly into pan and up sides. Dip a dry-measuring cup in flour, and use it to press dough firmly into bottom and against sides of pan. Freeze crust until firm, 10 to 15 minutes.
• Using a fork, prick crust all over. Bake until golden, 25 to 30 minutes, pressing down gently once or twice with a spoon during baking if crust puffs up. Cool completely in pan.
• Make the filling: In a medium bowl, mix cream cheese and remaining 1/4 cup sugar until smooth; spread mixture evenly in bottom of baked crust (still in tart pan).
• Starting from outside edge, arrange strawberry halves, stemmed side down, in tight concentric circles on cream cheese.
• In a small saucepan, heat jelly on medium-low until liquefied. Gently brush strawberries with jelly; let set at least 20 minutes. Chill in pan at least 1 hour (and up to 6 hours); remove from pan just before serving.

Steps:

• Brush a 9-by-13-inch baking dish with vegetable oil. Line dish with parchment paper, leaving a 2-inch overhang on 2 sides; oil parchment. Set dish aside.
• Pour 2/3 cup cold water into the bowl of a stand mixer fitted with the whisk attachment. Sprinkle with gelatin; let stand until softened, 5 minutes.
• Stir together granulated sugar, jam, corn syrup, salt, and 1/2 cup water in a medium saucepan. Bring to a boil, stirring often. Continue to boil until syrup registers 238 degrees on a candy thermometer (soft-ball stage).
• Add syrup to gelatin. Beat on low speed until slightly cooled. Gradually raise speed to high, beating until mixture is cool and peaks form, 30 to 40 minutes. Mix in red food coloring, one drop at a time, to achieve desired shade of pink.
• Pour mixture into prepared pan; smooth surface. Let stand, uncovered, until firm, about 3 hours or overnight.
• Dust a cutting board with confectioners' sugar. Run a knife around edges of marshmallow to loosen; unmold onto cutting board. Peel off parchment. Lightly coat a large sharp knife with oil; cut marshmallow into 1 1/2- to 2-inch pieces, coating knife with more oil as necessary. Dust with confectioners' sugar; toss to coat completely.

Steps:

• Prepare the strawberries by wiping them with a piece of damp kitchen paper. (Wiping the strawberries rather than washing them ensures the fruit doesn't absorb lots of water - too much water and the jam won't set easily.) To hull the fruit, use a knife to cut a cone shape into the strawberry and remove the stem. Cut any large berries in half.
• Put the strawberries in a bowl and gently toss through the sugar. Leave uncovered at room temperature for 12 hrs or overnight. This process helps the sugar to dissolve, ensures the fruit doesn't disintegrate too much and helps to keep its vibrant colour.
• Before starting the jam, put 2 saucers in the freezer. Tip the strawberry mixture into a preserving pan with the lemon juice. Set over a low heat and cook very gently. If any sugar remains on the sides of the pan, dip a pastry brush in hot water and brush the sugar away.
• When you can no longer feel any grains of sugar remaining, turn up the heat to start bubbling the jam and bringing it to the boil. (The sugar must be completely dissolved before increasing the heat, otherwise it will be difficult for the jam to set, and it may contain crystallised lumps of sugar.)
• Boil hard for 5-10 mins until the jam has reached 105C on a preserving or digital thermometer, then turn off the heat. If you don't have a thermometer, spoon a little jam onto one of the cold saucers. Leave for 30 secs, then push with your finger; if the jam wrinkles and doesn't flood to fill the gap, it is ready. If not, turn the heat back on and boil for 2 mins more, then turn off the heat and do the wrinkle test again. Repeat until ready.
• Use a spoon to skim any scum that has risen to the surface and discard this. Do this only once at the end, rather than constantly during the boiling stage, to reduce wastage.
• Add a knob of butter, if you like, to the finished jam, and stir in to melt. This will help to dissolve any remaining scum that you haven't managed to spoon off the top. Leave the jam to settle for 15 mins - this will ensure that the fruit stays suspended in the mixture and doesn't all float to the top of the jam jar. Meanwhile, sterilise your jars.
• Ladle into warm jars, filling to just below the rim. Place a wax disc on top of the jam (this prevents mildew forming), then cover with a lid or a cellophane circle and elastic band. Pop on a label (include the date), plus a pretty fabric top, if you like. The jam can be stored for up to 1 year in a cool, dry place. Refrigerate after opening.
