Step 1

Mix the mulberries, lemon juice, and sugar in a pot.

Step 2

Cook, stirring, for about 20 to 30 minutes or until thick.

Step 3

While the jam is cooking, put a small plate in the freezer.

Step 4

After 20 minutes, when the jam appears like it is beginning to gel, put the fire off.

Step 5

Put a small amount of jam on the frozen plate and return it to the freezer for a few minutes. If it wrinkles when you nudge it, it’s ready. If not, cook it some more and test it again until it’s ready.

Step 6

Store the jam in sterilised jars.
