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).
French cuisine
Visual display was prized. Brilliant colors were obtained by the addition of, for example, juices from spinach and the green part of leeks. Yellow came from saffron or egg yolk, while red came from sunflower, and purple came from "Crozophora tinctoria" or "Heliotropium europaeum". Gold and silver leaf were placed on food surfaces and brushed with egg whites. Elaborate and showy dishes were the result, such as "tourte parmerienne" which was a pastry dish made to look like a castle with chicken-drumstick turrets coated with gold leaf. One of the grandest showpieces of the time was roast swan or peacock sewn back into its skin with feathers intact, the feet and beak being gilded. Since both birds are stringy, and taste unpleasant, the skin and feathers could be kept and filled with the cooked, minced and seasoned flesh of tastier birds, like goose or chicken.
