Mirepoix (cuisine)
Similar flavour bases include the Italian "soffritto", the Spanish "sofrito", "refogado/sufrito" (braised onions, garlic and tomato) from Portuguese-speaking nations, the German "suppengrün" (leeks, carrots and celeriac), the Polish "włoszczyzna" (leeks, carrots, celery root and parsley root), the US Cajun / Creole holy trinity (onions, celery and bell peppers), and possibly the French "duxelles" (mushrooms and often onion or shallot and herbs, reduced to a paste).
Auguste Escoffier
Georges Auguste Escoffier (; 28 October 1846 – 12 February 1935) was a French chef, restaurateur and culinary writer who popularized and updated traditional French cooking methods. Much of Escoffier's technique was based on that of Marie-Antoine Carême, one of the codifiers of French "haute cuisine", but Escoffier's achievement was to simplify and modernize Carême's elaborate and ornate style. In particular, he codified the recipes for the five mother sauces. Referred to by the French press as "roi des cuisiniers et cuisinier des rois" ("king of chefs and chef of kings"—though this had also been previously said of Carême), Escoffier was France's preeminent chef in the early part of the 20th century.
