Ingredients:

  • 4 cups (950g) crushed strawberries or mixed berries
  • 1 tbsp (15ml) lemon juice
  • 2 cups (400g) cane sugar
  • 1 box (57g) powdered pectin

Instructions:

  1. Place a small ceramic plate or two metal spoons in the freezer to ensure the surface is ice-cold for the set test.
  2. Combine the crushed fruit and lemon juice in a heavy-bottomed pot.
  3. Stir in the powdered pectin until completely dissolved.
  4. Gradually add the cane sugar, stirring constantly over medium-high heat.
  5. Bring the mixture to a full rolling boil that cannot be stirred down.
  6. Perform the freezer plate test by spooning a small amount of hot jam onto the chilled plate and letting it sit for 30–60 seconds.
  7. Push the edge of the jam with your finger; if the surface wrinkles and holds its shape (the flake test), the jam is done.
  8. If the jam flows back like syrup, boil for another 2 minutes and repeat the test.
