Cozido à portuguesa: the great boiled dinner
Portugal (national)
Portugal's supreme boiled dinner — a vast pot containing multiple meats (fresh pork, salted pork, chouriço, morcela, alheira, chicken, beef), vegetables (potato, carrot, turnip, couve), and dried chickpeas and white beans, all cooked in the same pot and served in sequence like the Spanish cocido madrileño, from which it descends and to which it is related through their shared Moorish heritage.
Each region of Portugal has its variant: Cozido à transmontana from the north uses smoked meats and local varieties; cozido das Furnas from the Azores is cooked in volcanic thermal springs. The national dish, if there is one, is this.
