Make this simple, three-ingredient raspberry jam at home. This recipe works well for small batches and thickens naturally without added pectin, perfect for toast, yogurt, or baking.

Ingredients

Scale
  • 4 cups fresh or frozen raspberries
  • 3 cups granulated sugar
  • 1 tablespoon fresh lemon juice

Instructions

  1. Prepare your jars and lids if you plan to can the jam. If freezing, ensure you have freezer-safe containers ready.
  2. Combine the raspberries and sugar in a heavy-bottomed saucepan. Let the mixture sit for 15 minutes to allow the sugar to draw out the juices from the berries.
  3. Place the saucepan over medium-high heat. Stir constantly until the sugar dissolves completely and the mixture begins to boil.
  4. Once boiling, add the lemon juice. Continue to boil, stirring frequently to prevent scorching, until the jam reaches the setting point. This usually takes 15 to 25 minutes. You can test the set by placing a small spoonful on a chilled plate; if it wrinkles when pushed, it is ready.
  5. Remove the jam from the heat. Skim off any foam that has formed on the surface using a spoon.
  6. For seedless jam, press the mixture through a fine-mesh sieve now, returning the pulp to the pot. If you prefer seeds, skip this step.
  7. Ladle the hot jam into your prepared jars, leaving 1/4 inch headspace. Wipe the rims clean.
  8. For refrigerator storage, let the jam cool, then seal and store in the refrigerator for up to three weeks. For longer storage, process the jars in a boiling water bath for 10 minutes, then cool and store. For freezer jam, cool completely before sealing and freezing for up to one year.

Notes

  • This recipe yields about 3 half-pint jars of jam. Adjust quantities for larger batches.
  • Using frozen raspberries is fine; do not thaw them before cooking.
  • The lemon juice helps the jam set and brightens the berry flavor.
  • For the best results when canning raspberry jam, use proper canning jars and follow safe canning procedures.
