Ingredients:

  • 4 cups (600g) mixed berries
  • 1 cup (200g) cane sugar
  • 2 tbsp (30ml) lemon juice
  • 1/4 tsp (1.5g) salt

Instructions:

  1. Rinse the berries under cold water and pat them dry.
  2. Combine the berries, sugar, lemon juice, and salt in a heavy-bottomed stainless steel pot. Stir gently and let the mixture sit for 10 minutes to release natural juices.
  3. Place the pot over medium-high heat and bring to a rolling boil, stirring constantly to prevent sugar from sticking.
  4. Reduce heat to medium and simmer, skimming off any white foam from the surface for a glossy finish.
  5. Insert a digital thermometer and cook until the mixture reaches 220°F (104°C).
  6. Perform the plate test by dropping a small spoonful of jam onto a frozen plate; wait 30 seconds and push with a finger to ensure the surface wrinkles.
  7. Remove from heat and pour the hot jam into sterilized jars, leaving 1/4 inch of headspace.
  8. Seal with lids and allow to cool completely at room temperature before refrigerating.
