Use rhubarb whole stalks or pieces. Choose, firm, tender, well-colored stalks with good flavor and few fibers. Wash, trim and cut into 1- or 2-inch pieces in lengths to fit the package. Heat rhubarb in boiling water for 1 minute cool promptly in cold water to retain color and flavor. Drain well.

Unsweetened pack: Pack either raw or preheated rhubarb tightly into containers without sugar. Leave 1/2-inch headspace. Seal, label and freeze.

Syrup pack: Pack either raw or preheated rhubarb lightly into containers; cover with cold 50-percent syrup (1 cup sugar to 1 cup water). Leave 1/2-inch headspace. Seal, label and freeze.

Puree: Prepare rhubarb as for rhubarb stalks or pieces. Add 1 cup water to 1 1/2 quarts (2 pounds) rhubarb and boil 2 minutes. Cool and press through a sieve. To 1 quart (2 pounds) puree, mix 2/3 cup sugar. Pack into containers leaving 1/2 inch headspace. Seal, label and freeze.
