How do you fix a stiff jam?

Stiff jams or jellies can also be warmed for use as pancake or ice cream syrups. Stiff jams or jellies can be thinned with water or fruit juice. They may or may not form a gel again once they are re-heated, as over-cooking of pectin can reduce or destroy its ability to form the gel structure.

Why is my homemade jam so thick?

Should you stir jam while it's boiling?

Do no stir jam once boiling, but use a wooden spoon to check it is not sticking on the base of the pan. Stirring lowers the temperature and delays setting point being reached. It is wasteful to remove scum too often. Do it at the beginning and at the end.

Boiling preserves beyond the gel point (longer than a few minutes) or uneven heat distribution from lack of stirring or a pot that's too small can all cause pectin to break down.
