Q1: What cut of meat does Birrieria El Primo use for its birria de res?
A1: The kitchen primarily utilizes beef chuck roll and beef shank. Chuck provides the essential intramuscular marbling required for tenderness during an eight-hour braise, while the bone-in shank contributes marrow and collagen, which gives the dipping broth its velvety, full-bodied viscosity.
Q2: How does authentic Jalisco style birria differ from the tacos served at El Primo?
A2: Traditional Jalisco birria is made from goat (chivo), served as a plated bowl of shredded meat sitting in soup alongside a stack of dry, warm tortillas. El Primo serves the Tijuana-adapted evolution, which substitutes beef, griddles the tortillas directly in skimmed braising fat with melted cheese, and serves the broth on the side for dipping.
Q3: Is the red oil on the tortillas spicy?
A3: The red color comes from the natural oils extracted from guajillo and ancho chilies during the cooking process. These specific varieties are chosen for deep red color, mild sweetness, and earthy fruitiness rather than raw heat. The actual spiciness is mild-to-medium; additional chile de árbol salsa can be added at the table for higher heat.
