Making your own chorizo is easier than you might imagine. Chef Saad likes the smoky, dried-cherry-like flavor that guajillo chiles add to the meat mixture, as well as the clean heat of chile árbol. For the queso fundido, he uses a blend of three cheeses: the creamy queso quesadilla, Monterey Jack, and grated Cotija, whose nutty flavor has led to its being dubbed Mexican parmesan.
