The word snail is usually used as a synonym for slug, but the difference between the two is that the snail has its shell and the slug doesn’t.
For those who don’t understand the difference, try cooking a slug stew without shells…..Harry Potter did it.
In Ferrara, the snails are cleaned, cooked, then taken out of their shells and spiced. They are accompanied by mushrooms and tomatoes, served together with a tasty sauce.
The process is long and laborious, but the final result is exquisite.
