Definition: The use of foam in cuisine has been used in many forms in the history of cooking. For example, whipped cream, meringue, and mousse are all foams. In these cases, the incorporation of air or another gas creates a lighter texture and/or different mouth feel. More recently, foams have become a part of molecular gastronomy technique. In these cases, natural flavors (such as fruit juices, infusions of aromatic herbs, etc) are mixed with a neutrally-flavored gelling or stabilizing agent such as agar or lecithin, and either whipped with a hand-held immersion blender or extruded through a whipped cream canister equipped with N₂O cartridges. Such foams add flavor without significant substance, and thus allow cooks to integrate new flavors without changing the physical composition of a dish.^[1] Some famous food-foams are foamed espresso, foamed mushroom, foamed beet and foamed coconut. An espuma or thermo whip is commonly used to make these foams through the making of a stock, creating a gel and extruding through the N₂O canister.^[2]

Definition: A foam is a substance that is formed by trapping pockets of gas in a liquid or solid. A bath sponge and the head on a glass of beer are examples of foams. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas.

An important division of solid foams is into closed-cell foams and open-cell foams. In a closed-cell foam, the gas forms discrete pockets, each completely surrounded by the solid material. In an open-cell foam, the gas pockets connect with each other. A bath sponge is an example of an open-cell foam: water can easily flow through the entire structure, displacing the air. A camping mat is an example of a closed-cell foam: the gas pockets are sealed from each other, and so the mat cannot soak up water.

Foams are examples of dispersed media. In general, gas is present in large amount so it will be divided in gas bubbles of many different sizes (the material is polydisperse) separated by liquid regions which may form films, thinner and thinner when the liquid phase is drained out of the system films.^[1] When the principal scale is small, i.e. for a very fine foam, this dispersed medium can be considered as a type of colloid.

The term foam may also refer to anything that is analogous to such a foam, such as quantum foam, polyurethane foam (foam rubber), XPS foam, Polystyrene, phenolic, or many other manufactured foams. This is not the purpose of this page.
