Authentic Mexican Street Tacos

Ingredients

• Flank steak (1 lb)
• Salt (1 teaspoon)
• Black pepper (1 teaspoon)
• Garlic powder (1/2 teaspoon)
• Chili powder (1 teaspoon)
• Cumin (1/2 teaspoon)
• Sour cream (1/2 cup)
• Salsa (1 cup)
• Avocado (1, sliced)
• Radishes (4, sliced)
• Onion (1 small, diced)
• Cilantro (1/2 cup, chopped)
• Lime (2, cut into wedges)
• Corn tortillas (8)

Instructions

1. In a small bowl, combine salt, pepper, garlic powder, chili powder, and cumin to create your taco seasoning.
2. Massage the seasoning into the flank steak, ensuring it's thoroughly coated. Let it marinate in the refrigerator for at least 1 hour, or overnight for deeper flavor infusion.
3. When ready to cook, preheat a grill or grill pan over medium-high heat.
4. Grill the marinated flank steak for 4-5 minutes per side, or until it's cooked to your preference. For a perfect medium-rare steak, ensure the internal temperature reaches 135°F.
5. Remove the steak from the grill and let it rest for 5 minutes. This resting period allows the juices to redistribute, leaving you with a moist, tender steak.
6. Slice the steak into thin strips against the grain. This technique ensures each piece is tender and easy to chew.
7. Heat the corn tortillas on the grill or in a dry skillet over medium heat until they're soft and pliable. Keep them warm in a clean tea towel until ready to serve.
8. Assemble the tacos by placing steak slices on each tortilla, followed by a sprinkle of diced onion, chopped cilantro, radish slices, and avocado slices. Top with a spoonful of salsa and a dollop of sour cream.
9. Serve the tacos immediately with lime wedges on the side. The final, crucial step is to squeeze the lime over the tacos for a zesty finish that ties all the vibrant flavors together.
