At its core this classic Roman dish could not be more simple — pasta with a spicy tomato sauce — but it’s a quintessential example of a dish that evolves over the course of its short cooking time into more than just what you put in the pot. And what you put in the pot is open to some interpretation. Arrabiatta sauce can be made with many different kinds of peppers. In my research when developing this recipe, I came across recipes that called for whole dried peppers, fresh chile peppers of all types, and chopped Calabrian chiles (a personal favorite of mine). In order to make this recipe as pantry-friendly as possible, I opted for a spice present in many cabinets: red pepper flakes. You should feel free to choose your own adventure here and add your favorite spicy pepper to the sauce if you like. Who am I to tell you how to put the “angry” in your arrabiata?
