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).
Nouvelle cuisine
Nouvelle cuisine (French, "new cuisine") is an approach to cooking and food presentation in French cuisine. In contrast to cuisine classique, an older form of haute cuisine, nouvelle cuisine is characterized by lighter, more delicate dishes and an increased emphasis on presentation. It was popularized in the 1960s by the food critics Henri Gault, who invented the phrase, and his colleagues André Gayot and Christian Millau in a new restaurant guide, the Gault-Millau, or "Le Nouveau Guide".
