The food in Asturias is in its own category when it comes to the cuisine in Spain. When most people think of the food in Spain, there's the egg omelet (tortilla), tapas (small bites of food) and paella (a rice dish from the Mediterranean). But in the north, due to the Celtic influence, the food is quite different from the rest of Spain.
I haven't tried very many different types of foods yet, but what I've had has been very good. As Asturias is on the coast, it has a wealth of seafood, and so I've had mussels cooked in a tomato sauce (mejillones), salted codfish (bacalao) and salmon. The region is also well known for its cheeses because of the cows that live in the mountains of the southern part of the region. My favorite food from Asturias would have to be cachopo, which is a fried meat fillet with slices of local cheeses and jamón (Spanish ham) fried together. It's so good and so large that it's a good meal to share with friends.
