How to check if the jam is set:

  • Place in the freezer for 2-3 minutes.
  • Check by pushing the jam with your finger, if it wrinkles slightly and it separates it is done.

Steps

  • Place a small plate in the freezer, you will need it to check if the jam is ready. Remove the black seeds from the watermelon, if necessary. Remove the rind. Chop and puree the watermelon pulp with an immersion blender. Strain through a sieve to remove the white seeds, optional.

  • Place in a large pot with the sugar and lemon juice. Bring to a boil. Sprinkle the pectin over the insides of the pot and whisk it in carefully to make sure that there are no clumps. Bring to a boil again, turn down the heat and simmer for about 20 minutes, stirring often.

  • Check to see if the jam is set. Remove the pot from the heat while you do that so that it doesn’t overcook. Pour a very small amount of jam on the plate, about ½ teaspoon or so. Place in the freezer for 2-3 minutes. Check by pushing the jam with your finger, if it wrinkles slightly and it separates it is done. If the jam is still rather liquid and comes back together after you push it, continue cooking for about 5 minutes, then check again.
