Method
Whisk the lime juice, lime zest, and salt in a large bowl until the salt dissolves.
Add the seafood, sliced red onion, radishes, and ground chiles to the lime mixture.
Toss the ingredients thoroughly to ensure the seafood is evenly coated in the marinade.
Allow the mixture to marinate at room temperature for 5 minutes.
Place the sliced avocado onto the surface of each corn tostada.
Gently fold the chopped cilantro into the marinated seafood mixture.
Using a slotted spoon, lift the seafood from the marinade and pile it on top of the avocado on each tostada.
Drizzle each tostada with salsa macha and serve immediately.
Chef's Notes
- For the freshest flavor, use high-quality, sushi-grade seafood if possible. Ensure it's very fresh as it will be 'cooked' by the lime juice.
- Don't over-marinate the seafood. The 5-minute marination time is crucial to lightly 'cook' the seafood without making it tough or mushy.
- Taste the marinade before adding the seafood and adjust salt and chile levels to your preference. The chiltepine chiles offer a unique, sharp heat.
- If you can't find chiltepine chiles, use a pinch of cayenne pepper or a finely minced serrano chile for heat, but be mindful of the flavor difference.
- Serve immediately after assembly to ensure the tostadas remain crisp and the seafood is at its freshest.
Storage
Refrigerator: 4 hours — The acid in the lime juice will continue to cook the seafood, eventually making it rubbery.
