Spaghetti alla chitarra is the one kind of spaghetti easy to make by hand, thanks to a wire-stringed 'guitar' (chitarra) that cuts the pasta sheets into uniform, squarish strands. A favourite all over central Italy, where it is considered the perfect pasta for rich meat and game sauces, and also in the south, where it goes equally well with seafood.
There's a different name for it in every corner, each with its own quirks, and sometimes made without a chitarra
