A true-blue classic, this Roman Cacio e Pepe recipe honors authenticity in its preparation and three-ingredient method. I give it my own spin by oven-toasting the noodles before boiling them, which adds a nutty depth of flavor to the finished dish. That said, it’s totally optional.
For the Peppercorns: I crush my peppercorns in a mortar and pestle (if I can find mine), or just on a rimmed baking sheet, using a heavy implement such as the bottom of a heavy pint glass or rolling pin. There’s no “right” way to crush peppercorns, but there are several ways that I tend to lean on. The baking sheet + heavy glass is usually the winner.
