Mushroom foam is created when a liquefied mixture is combined with air or other light gases to create a foam that resembles thick soap bubbles. A number of nontraditional foams have been created through the development of molecular gastronomy. Mushroom foam can be added to recipes to provide the food with the taste of mushrooms in cases where the diners do not like the texture of mushrooms. Chef Michael Callahan has developed the following recipe for mushroom foam, which he uses in his restaurant.
