Jelly is an item of food having a soft, firm, somewhat elastic texture either created by the pectin in fruit or the gelatin in meat.
Pectin jelly is a combination of fruit juice and sugar that has been cooked, usually with pectin, to make a clear, thick preserve. Apple, cherry, grape, red currant, and strawberry are among the prepared varieties commonly available. Fruit jellies can be used to make glazes.
Meat jellies (Aspic) are pieces of meat set in gelatin.
Jelly is also made with gelatin, sugar and fruit flavours (Jell-O)
