Pick over, wash, drain, and hull strawberries; then weigh. Fill glass jars with berries. Make a syrup same as for Damson Preserve, cooking the syrup fifteen minutes. Add syrup to overflow jars; let stand fifteen minutes, when fruit will have shrunk, and more fruit must be added to fill jars. Screw on covers, put on a trivet in a kettle of cold water, heat water to boiling-point, and keep just below boiling-point one hour.
