Confession: As a child, I always assumed tuna was a little fish because it came in little cans. I never imagined the 3-footer marine creatures that they actually are. But it’s no secret that some little fish do come in cans — in this case, sardines — for there are plenty of fish in the sea (just not all are suited to be served in metal containers).
To some people, canned fish may have a bit of stigma attached to it — the can automatically denotes that the fish is not fresh. But for others, it’s a completely normal and delicious way to transport seafood, especially when you don’t live near a coast. In fact in inland Spain, canned seafood, or latillas as they are called (literally “little cans”), is very much part of the gastronomic culture in the home and in tapas bars.
