Ravioli Stuffed with Fava Beans, Ricotta, and Mint with Brown-Butter Sauce
You can substitute fresh or frozen peas for the fava beans. Drain the ricotta in a sieve set over a bowl for about 10 minutes to remove excess liquid. Try to find the denser buffalo ricotta for this recipe. If you use regular ricotta, the filling won't be as thick.
