1 pint ripe blackberries.

1/2 cupful sugar.

1 pint water.

1 tablespoonful cornstarch.

Whipped cream.

Simmer together the blackberries and water. Do not stir. Mix cornstarch with just a little cold water and stir in carefully. Do not break the fruit. Let it cook for five minutes, remove, add the sugar, and when cool pour into glasses. Serve ice cold with a heaping tablespoonful of whipped cream on each glass.
