Mexican adobada, a tangy marinade with guajillo chiles, is often reserved for large cuts of pork, but it’s also well-suited to any sturdy cut of steak, such as flank. The acid comes from lime juice in this formula, but vinegar or lemon juice works as well. An overnight marinade yields incredibly tender results, but a 30-minute steep is sufficient to infuse the meat with the fruity flavor of the chiles. Here, the steak is paired with a nice piquant roasted red pepper relish, which complements the deep flavors of the marinated meat. Side dishes like rice, beans and warm tortillas round this dish out for a wonderful weeknight meal.
