Duxelles
Use white button mushrooms. Refrigerate for up to three days, or freeze in 1/4-cup portions (try using muffin tins) for up to three months. Thaw frozen duxelles before adding them to a recipe. Duxelles give earthy, aromatic notes to meat and fish stuffings, soups, stews, pastas, and casseroles.
