Instructions

1. Step 1: Combine 2 tsp kosher salt, 2 tsp black pepper, 1 tbsp smoked paprika, 1 tsp cayenne pepper, and 1 tsp garlic powder in a small bowl. Rub this spice mix evenly over a 2 lb trimmed beef brisket flat.
2. Step 2: Preheat a grill to medium heat (about 350°F). Place the brisket on the grill and cook for 1.5 to 2 hours, turning occasionally, until the internal temperature reaches 195°F and the meat is tender.
3. Step 3: While the brisket cooks, prepare pickled onions by combining 1/2 cup apple cider vinegar, 1/2 cup water, and 1 tbsp sugar in a small saucepan. Bring to a simmer until sugar dissolves, then pour over 1 thinly sliced medium red onion in a jar. Let sit at room temperature for at least 30 minutes.
4. Step 4: Once the brisket is cooked, let it rest for 15 minutes, then slice thinly against the grain.
5. Step 5: Warm 12 small corn tortillas on the grill for 30 seconds per side until pliable.
6. Step 6: Assemble tacos by layering sliced brisket, pickled onions, and 1/4 cup fresh cilantro leaves on each tortilla. Serve immediately with lime wedges to squeeze over.
