Blackberry Jam

Blackberry Jam, from
The Magazine of Domestic Economy (1837)

Delicious seasonal food preservation: Blackberry Jam, from The Magazine of Domestic Economy (1837).  The receipt is quite simple: blackberries, sugar, and optional lemon peel or juice. Simmer for 45 minutes.

For this batch, I used 4 pounds of blackberries, 2 pounds of granulated sugar, and the peel of 1/3 of a lemon. It yielded 3.5 pints, and is quite tasty. The canning jars are, of course, modern. I opted to follow current food safety standards and process the jars for 10 minutes in boiling water.
