Arrange strawberries in two layers in a large kettle. Sprinkle the layers with an equal amount of sugar. Permit to stand for 30 minutes. Heat over low heat until boiling, then simmer for 15 minutes. Pour the berries onto platters. Cover loosely with glass or plastic dome, out of the reach of insects. Permit the berries to stand in the sun for 2 or 3 days, until the juice forms a jelly. Turn the berries very gently twice a day. These preserves need not be reheated. Place in hot sterilized glasses and seal. Serve with a smile!
