Spiced meat wrapped in maguey membrane and steamed for celebrations is a Central Mexican feast. This high protein, family dish is a fresh, tender, aromatic centerpiece for gatherings.
Soak the dried guajillo and pasilla chiles in hot water for 15 minutes, then remove stems and seeds.
Blend chiles with onion, garlic, cumin, black pepper, oregano, vinegar, and salt until a smooth marinade forms.
Cut pork shoulder and beef chuck into 2-inch cubes and toss them in the marinade to coat thoroughly; marinate for at least 2 hours or overnight for deeper flavor.
Lay maguey leaves flat and place marinated meat evenly in the center of each leaf. Secure tightly by folding and tying with kitchen twine.
Arrange the wrapped mixiotes in a steamer, add bay leaves among parcels, cover and steam over medium-low heat for 2 hours, ensuring water is replenished to maintain steady steam.
