Pluot Jam Recipes

Steps:

• Toss fruit and sugar together in a large, heavy-bottomed pot. Let sit for at least 15 minutes or up to overnight, tossing periodically 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 skins burst and the juices start to boil, 10 to 15 minutes. If using a vanilla bean as an add-in, put it in the pot now.
• Increase the heat to medium-high. Cook the jam, stirring occasionally with a wooden spoon or spatula at first and more frequently as juices thicken until most of the liquid has evaporated and the fruit has begun to break down, about 25 to 35 minutes. How much it breaks down will depend on the type of fruit and how ripe it is. (For example, peaches are likely to retain their shape, while plums and apricots will break down almost entirely.)
• As the jam cooks, the liquid reduces, 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.
• When the jam reaches a slow, thick boil, add lemon juice and any of the add-ins (see note). Continue to cook, stirring constantly until the jam has returned to its previously thickened state, 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 it a few minutes more.
• Remove from heat, and pick out vanilla bean, if you added it earlier. Divide between jars, leaving 1/4 inch of space at the top of the jar, 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.

Steps:

• Place the plums and water into a large pot, and bring to a boil. Reduce heat to medium-low, cover, and simmer for 5 minutes. Stir in the sugar, and add butter to reduce foaming, if needed. Bring the mixture to a full, rolling boil over high heat, stirring constantly, and then mix in the pectin quickly. Return the jam to a full boil, and boil for 1 minute, stirring constantly. Remove from heat, and skim off and discard any foam.
• Sterilize the jars and lids in boiling water for at least 5 minutes. Pack the plum jam into the hot, sterilized jars, filling the jars to within 1/8 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 10 minutes.
• Remove the jars from the stockpot and place onto a cloth-covered or wood surface, several inches apart, until cool. 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. Refrigerate opened jars for up to 3 weeks.

Steps:

• Stir together plums, sugar, and 1/4 teaspoon salt in a large heavy-bottomed pot. Bring to a boil, stirring until sugar is dissolved and mashing plums with a potato masher. Add lemon juice; continue to boil, stirring frequently, until bubbles slow, chunks of fruit show at top, and mixture clings to a spoon but falls off in clumps, 10 to 12 minutes. Skim foam from top.
• Ladle jam into clean containers, leaving 3/4 inch of headroom. Let cool completely. Cover, label, and refrigerate up to 1 month, or freeze up to 1 year.

Steps:

• Combine all ingredients in a large saucepot.
• Bring to a boil, stirring until sugar dissolves.
• Cook rapidly almost to gelling point.
• As mixture thickens, stir frequently to prevent sticking.
• Ladle into hot jars, leaving 1/4 inch head space.
• Adjust two-piece lid caps.
• Process 15 minutes in a boiling water canner.

Steps:

• In a large pot combine peaches, plums, lemon juice and sugar.
• Cook, stiring, over med-high heat until sugar is melted.
• Bring to a rolling boil.
• Boil, stirring constantly, for 1 minute.
• Add 2 pouches of Certo, stirring constantly.
• Return to a rolling boil.
• Boil, stirring constantly for 1 minute.
• Remove from heat.
• Skim off any foam with a metal spoon.
• Fill Hot sterile jars leaving 1/4 inch headspace.
• Wipe off jar rims with damp cloth.
• Top with 2 piece seal and ring.
• Hot water bath jars for 10 minutes.
