Let stand until gelatine is soft. Add 1 pint boiling water, or fruit juice from canned fruit.
Stir until gelatine is dissolved. Add 1 cup leftover fruit. Place in mold which has been dipped in cold water. Stir occasionally while hardening so fruit does not settle to the bottom. Or a little gelatine may be poured in mold and allowed to grow almost hard; then some fruit arranged on it and more gelatine poured in. Repeat until mold is filled; then chill, and turn out carefully.
