The first reference to Ravioli dates back to the 1300s in Prato. Not long after, there is also reference made to Ravioli in Venice. Just 150 years or so later and they were being served in Rome as well.
The world ravioli is the plural of the singular raviolo. Not that you would ever want just one, as they are so delicious!
These fresh pasta delights can be stuffed with potato, cheese, spinach and ricotta, meat and other fillings. They take just a few minutes at most to cook in boiling salted water. They can be served with a simple sauce (like butter and sage or a light tomato sauce) or even in broth, although in many parts of Italy it would be more common to find tortellini in broth, being a form of smaller, folded ravioli.
