Short answer
You must try the Azorean fish and seafood specialties: grilled limpets (lapas), barnacles (cracas), octopus stew, tuna steak, and the famous cozido das Furnas (meat stew, but a must-try). For fish, look for fresh catches like wreckfish (cherne), grouper (garoupa), and swordfish. Seafood is often simply grilled with butter and garlic, letting the freshness shine. Don't miss the local clams (amêijoas) and the seafood rice (arroz de marisco). Pair with a glass of Azorean white wine. Confirm daily availability at local restaurants, as menus depend on the catch.
