Mushroom Pâté Crostini

Don't crowd the mushrooms - cook in batches if needed. Browning is essential for flavor. The sherry adds depth; dry vermouth works too. Process until very smooth for elegant texture. The pâté firms as it chills. Let sit at room temperature 15 minutes before serving for best spreadability.

Mushroom pâté emerged as a serious culinary preparation in the 1970s and early 1980s, as French nouvelle cuisine's influence spread and vegetarian and meatless preparations began to appear on restaurant menus with the same care previously reserved for meat. The key flavor principle behind mushroom pâté is that deeply browned mushrooms produce an intensity of glutamate — the amino acid responsible for umami — that approaches the savory depth of meat-based pâtés. This is particularly true of dried porcini mushrooms (Boletus edulis), which have been prized in Italian and French cooking since at least the Renaissance and which contain exceptionally high levels of glutamate and other umami compounds when dried. The technique of cooking down a mixture of mushrooms with aromatics, wine, and herbs to a spreadable consistency draws on the French tradition of duxelles, the classic mushroom preparation documented in François Pierre La Varenne's Le Cuisinier François (1651) and named after the Marquis d'Uxelles. La Varenne is credited with codifying much of classical French cooking in the 17th century, including this foundational preparation. The modern mushroom pâté adapts these techniques for an all-vegetable format, producing a spread that satisfies both vegetarian guests and anyone who appreciates the depth that properly cooked mushrooms can deliver.
