Earlier, I solicited culinary recommendations for a trip to the Azores. I found there is not a lot of information out there on this topic. Someone asked that I report findings after the trip, so here they are. I would highly recommend the Azores for foodies. Hopefully future travelers find this helpful.
Arruda Pineapple Plantation: Tastings of a delicious homemade pineapple liqueur are free.
Gorreana Tea Plantation: You can taste 6 kinds of tea.
Alianca: Popular with locals. The blood sausage here was cinnamony and velvety, like the inside of a chocolate truffle. It is served with pineapple. Also you can try grilled limpets (a mollusk/barnacle?), a specialty served sizzling hot & covered in garlic.
Restaurante Nacional: Try the regular sausage. All meals on this island were served with a delicious fresh cheese & pimento sauce.
Costa Do Atlantico: Lots of fresh fish, including something called squirrelfish (very light & fluffy).
O Jaime (not the one by the water): The owners don't speak English & are very friendly. Here we had lots of unusual fresh fish.
Tony's: The locals cook a stew underground near the hot springs. The stew contains pork, blood sausage, regular sausage, chicken, brisket, yam, potato, cabbage, & carrots.
My favorite food island, known for wine and one kind of cheese. Ask someone to take you to the shack where the cheese is produced. It seems everyone owns a vineyard - our guide took us to his! We tried his wine & fig brandy.
Ancoradeuro: Order the octopus stew - flavorful, fresh, & expertly cooked. My favorite!
O Luis: No one spoke English here and we pointed to random items on the menu. What we got was a delicious kind of lobster called cavaco, which is superior to our lobsters. Wine is cheap in this island. We got a pitcher of wine for $2.
Food is heartier here.
O Lima: Try the goat. This restaurant was full of locals watching soccer.
Medalhas: Great quail and ribs. Best meal on the island.
