Blackberry Jam Recipe 1 ingredients

To prepare this Blackberry Jam Recipe 1, first put the berries in a preserving kettle, cover closely and let become hot, then with a wooden pestle press through a sieve fine enough to keep back the seeds. Measure the pulp and for each two cups take one cup of sugar. Heat slowly to the boiling point, stirring often. Let cook nearly half an hour, stirring almost constantly. Store as canned fruit, or cook an hour or more and store as jelly. This makes a particularly good sauce for cornstarch puddings and the like.
