Tostadas de ceviche

Method

1. 1 Peel the shrimp, then split them lengthwise and soak them in ice-salt water for 15 minutes.
2. 2 Blend jalapeño peppers with lime juice and salt to make a clear green sauce.
3. 3 Soak the shrimp in the green sauce for 15 minutes until the meat turns opaque pink, indicating it's cooked by the acid.
4. 4 Soaking the shrimp for more than 25 minutes will make the meat mushy and dry, like overcooking.
5. 5 Fry whole corn tortilla leaves for 90 seconds until flat and crispy.
6. 6 Arrange the shrimp, cucumber wedges, red onion, and avocado on the pastry sheet, then sprinkle with herbs.
