ravioli

Ravioli are little pasta cushions with a filling inside. Two sheets of pasta, a spoonful of something, and sealed at the edges.

The filling is traditionally ricotta and spinach, or meat, or squash, and the shape is usually square with a crimped edge. Italian treats the word as plural, and English usually treats it as a mass noun, so most people say ravioli is rather than ravioli are. It sits in a large family of stuffed pastas including tortellini, agnolotti and the enormous single raviolo.
