Piping Gel is a good all-around cake decorating ingredient. It can be tinted with food coloring or colored with luster dust, and can be used for piping, flooding areas for a stained-glass effect, or warmed and poured as a glaze on cheesecakes and mousse cakes. It can also be used as a glaze for fresh fruit (on tarts or cakes), eclairs, and danishes. Finally, you can use it to stick fondant decorations together as a sort of edible glue.
