Buttercream the butter (which has a variable melting point below ) as it is subsequently beaten in. French buttercream (also known as pâte à bombe-based buttercream or common buttercream) is made with whipped egg yolks. Custard-based buttercream is prepared by beating together pastry cream and softened butter, and may be additionally sweetened with extra confectioners' sugar.

Simple buttercream is made by creaming together fats (butter, margarine, or vegetable oil shortening) and powdered sugar to the desired consistency and lightness. Typically twice as
Foam one large vacuole, thus the closed-cell foam of the moist dough is transformed into an open cell solid foam in the bread. The unique property of gas-liquid foams having very high specific surface area is exploited in the chemical processes of froth flotation and foam fractionation. Solid foams are a class of lightweight cellular engineering materials. These foams are typically classified into two types based on their pore structure: open-cell-structured foams (also known as reticulated foams) and closed-cell foams. At high enough cell resolutions, any type can be treated as continuous or "continuum" materials and are referred to as cellular
