A very good and easy recipe for jam which uses up the excess berries on the bushes and trees.
4 cups crushed berries (Mulberries are in season and very good)
4 cups sugar
To prepare fruit. Sort and wash berries. Crush the berries. Put very seedy berries through a sieve or food mill.
To make jam. Measure crushed berries into a pan or microwave proof dish. Add sugar and stir well. Boil rapidly, stirring constantly, to 9 degrees above the boiling point of water (221 degrees), or until the mixture thickens - if using microwave this will probably be about 25 minutes. Remove from heat; skim.
Fill and seal containers. This recipe yields 4 half-pint jars. To preserve for a longer period add a tablespoon of vodka or brandy to the finished jam.
