Large red raspberries. Sugar.

Pick over the berries carefully, keeping a sharp lookout for bugs.

Place them in clean jars in layers, alternating a layer of berries with a layer of sugar and using about three tablespoonfuls of sugar to one pint.

Place the jars, about two-thirds filled, on a rack in a washboiler. Pour in cold water until the jars are two-thirds covered. Put a cover on a boiler and place over a moderate fire. As soon as the water around the jars thoroughly boils, remove the jars one at a time and if the fruit has settled, fill from the other jars.

Seal immediately and set aside to cool.
