Creating Spicy Shrimp Tacos with Avocado Crema is straightforward and can be accomplished in a series of simple steps:

1. Prepare Shrimp: In a mixing bowl, toss the peeled and deveined shrimp with olive oil, chili powder, and cumin. Ensure the shrimp are well coated with the spices.
2. Cook Shrimp: Heat a skillet over medium heat. Sauté the seasoned shrimp for about 3-4 minutes, or until they turn pink and opaque. Stir occasionally to ensure even cooking.
3. Make Avocado Crema: While the shrimp cooks, cut the avocado in half and remove the pit. In a blender, combine the avocado, sour cream, lime juice, and a pinch of salt. Blend until smooth and creamy.
4. Warm Tortillas: Lightly heat the tortillas in a separate pan or microwave until warm and pliable, which helps in rolling them without breaking.
5. Assemble Tacos: Once the shrimp is cooked and the avocado crema is ready, place a generous amount of shrimp inside each tortilla.
6. Top It Off: Drizzle the avocado crema over the shrimp. Feel free to add any additional toppings like chopped cilantro or sliced radishes for extra flavor.
7. Serve Immediately: Enjoy your spicy shrimp tacos while they’re fresh and warm.
