Blackberry mush
To make
Blackberry mush, put the fruit in a preserving kettle, mash it to a pulp, with sugar enough to make it quite sweet. Set it over the fire, and, as soon as it begins to simmer, stir in very gradually two teaspoonsful of your to a quart of fruit. It should be stirred all the time it is boiling. Serve it either warm or cold, with cream.
Raspberries may be cooked in the same way.
