Crust (geology)

In geology, the crust is the outermost solid shell of a rocky planet or natural satellite, which is chemically distinct from the underlying mantle. The crusts of Earth, the Moon, Mercury, Venus, Mars, Io, and other planetary bodies have been generated largely by igneous processes, and these crusts are richer in incompatible elements than their respective mantles.

Crust (baking)

In baking, a crust is the outer, hard skin of bread or the shell of a pie. Generally, it is made up of at least shortening or another fat, water, flour, and salt. It may also include milk, sugar, or other ingredients that contribute to the taste or texture. An egg or milk wash can be used to decorate the outside, as well as coarse sugar. A crust contributes to a pastry.

Depending on the type of pastry, the crust can be baked before it is filled, or in baked (baked together with the filling). In pies, two different types of crust exist: one-crust pie and two-crust pie. A two-crust pie can have either a complete upper crust, a lattice top, or any of a variety of other decorative tops.
