It's hard to imagine a taco without a chunky, tomato-based sauce, yet too often we don't give much thought to the red (or green) stuff. Making your own salsa can be as simple as chopping tomato, onion and some jalapeño—and making minor tweaks to the formula can yield massive results in the flavor department. Try adding tomatillos (
this recipe uses them exclusively) or, as chef Alex Stupak, author of
Tacos: Recipes and Provocations, suggests, use roasted onion, for a subtly sweet flavor.
