Carne asada norteña

Method

1. 1 Marinate the beef slices (1 cm thick) with lemon juice, beer, and coarse salt for 2 hours, making sure not to add any oil so that the meat surface doesn't dry out and catch fire.
2. 2 Burn the charcoal until it's covered in white ash, then fan it until it glows red before placing the grill rack down.
3. 3 Grill the meat for 2 minutes on each side over the highest heat; the meat is thin, so if you're 30 seconds slower, it will dry out.
4. 4 Grill whole scallions and green bell peppers for 6 minutes over medium heat.
5. 5 Chop the meat directly on a wooden cutting board, then wrap it in a tortilla with avocado, onion, and grilled peppers.

With an appliance

• Oven 35 min

  Replace step 3: Place the beef on the top rack of a 240-degree oven on a preheated grill, cook for 3 minutes on each side, then let it rest for 5 minutes; keep the vegetables from step 4 as is. The oven cooks the meat more evenly but doesn't produce the strong smoky flavor of the original.
