Answer 1

Fruit Preserves, Jams, And Jellies

The making of jellies and other preserves is an old and popular process, providing a means of keeping fruits far beyond their normal storage life and sometimes making use of blemished or off-grade fruits that may not be ideal for fresh consumption. In jelly making, the goal is to produce a clear, brilliant gel from the juice of a chosen fruit. Jams are made from the entire fruit, including the pulp, while preserves are essentially jellies that contain whole or large pieces. Marmalade, usually made from citrus fruit, is a jellylike concentrate of prepared juice and sliced peel.
