Shortening

Shortening A solid fat made from vegetable oils typically used to make pie crusts flaky. Virtually tasteless, you can substitute vegetable shortening for other fats in baking. Some companies also make a butter flavored shortening which is especially popular for baking and pie crusts.

While made from oil, shortening has been hydrogenated into a solid state, a process which creates trans-fatty acids and converts the mixture to a saturated fat. It can also be melted and used for frying. It is excellent for greasing pans, as it does not easily burn and is practically tasteless.
