Shrimp Tostadas

Crema Sauce: 
1/2 cucumber, peeled and cut into a very small dice 
Juice from 2 limes
1/2 cup Mexican crema

Vegetable oil 
6 to 8 tortillas 
1/2 pound medium-sized shrimp, peeled and deveined 
Juice from 2 limes
1/2 avocado, diced 
Hot sauce 

1. In a small bowl, add the cucumber and sprinkle with a few pinches of salt. Allow to stand for 5 minutes to release some of its water. Squeeze in the lime juice and quickly mix in the crema. Salt to taste. Place in the refrigerator while you prepare the rest of the dish. 

2. In a cast iron skillet (or a sauté pan), add about 1-inch of oil. Heat the oil over medium-high heat; when the oil is hot add the tortillas, in batches, and fry until crispy, flipping them at the 30-40 second mark. Transfer the tortillas to a bed of paper towels and sprinkle both sides with a bit of salt. Repeat frying step with the remaining tortillas. 

3. In a saucepan, boil the shrimp for 30-40 seconds minute, until pink and a bit undercooked (we're going to toss them with lime juice, which will cook them a bit more). Transfer the shrimp to a cutting board and allow to sit until they're cool enough to handle. Slice the shrimp in half, horizontally. Add the shrimp to a bowl and toss with a few pinches of salt and the juice from the limes. Transfer to the fridge to chill for 10 to 15 minutes. 

4. To assemble, add a few tablespoons of crema/avocado sauce to each tostada. Top with a few shrimp, a scoop of diced avocado and a couple dashes of hot sauce. Repeat with the remaining tostadas. 

Yields 6 to 8 tostadas; Serves about 4 people
