This is a recipe that I found on Serious Eats and adapted to our tastes. Here’s the original website https://www.seriouseats.com/penne-pasta-arrabbiata-sauce-recipe. We changed it up a bit because we like our spiciness coming from various sources—the red pepper flakes for overall heat, Tabasco for front of the mouth spiciness, and Sriracha for zingy sweetness.
The original recipe says it serves six but that is less than 3 ounces a person. That’s definitely not enough for us! We made all the sauce for 8 ounces of pasta. There was some sauce left over but that is always okay in our house. Someone will always find a use for it.
