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 fries
"Frites" are the main ingredient in the Canadian/Québécois dish known (in both Canadian English and French) as "poutine"; a dish consisting of fried potatoes covered with cheese curds and brown gravy. Poutine has a growing number of variations but is generally considered to have been developed in rural Québec sometime in the 1950s, although precisely where in the province it first appeared is a matter of contention. Canada is also responsible for providing 22% of China's French fries.
