How to Make It
Sprinkle beef with 1 teaspoon pepper and 1 teaspoon salt. Heat a large Dutch oven over medium-high heat. Add 1 teaspoon oil to pan; swirl to coat. Add one-quarter of beef to pan; sauté 3 minutes or until well browned on all sides. Remove beef from pan. Repeat procedure 3 times with 3 teaspoons oil and remaining beef.
Add remaining 1 teaspoon oil to pan; swirl to coat. Add onion and next 8 ingredients (through dried chile); sauté 3 minutes. Stir in remaining 1 teaspoon black pepper, remaining 3/4 teaspoon salt, and tomato paste; cook 1 minute, stirring constantly. Stir in 4 cups water and beer; bring to a simmer. Reduce heat to medium-low, cover, and cook 2 hours or until beef is very tender. Combine remaining 1/2 cup water and masa in a small bowl, stirring with a whisk until smooth. Add masa mixture and hot sauce to pan; cook 3 minutes or until slightly thickened. Discard dried ancho chile and bay leaves. Sprinkle with green onions.
