Premium canned or tinned food can be preserved without using additives or artificial ingredients, which makes it a healthy alternative. They provide a great source of nutrient rich protein for meals and can be showcased in their natural juices, in olive oil, or in a variety of regional sauces. Spain specializes in high-end tinned fish and seafood from different regions of the country such as Galicia, Cantabria, Basque country, Cataluña and Asturias amongst others.
Since the ingredients in a tin are already cooked, they require no prep time and maintain their quality year round. This fast alternative can be kept on hand as a pantry staple and allows cooks to constantly have a variety of seafood such as tuna, clams, sardines, octopus, and squid or to keep seasonal vegetables such as white asparagus, piquillo peppers or Basque chili peppers.
