Instructions

Short Description:
Crisp corn tostadas topped with bright Jalisco-style ceviche of lime-cured shrimp mixed with diced tomatoes, onion, cilantro, serrano, and creamy avocado for a contrast of texture and fresh flavors.

Regional Notes:
This Jalisco variation highlights local seafood—typically fresh shrimp or nearby coastal fish—cured briefly in lime and mixed with simple vegetables (tomato, onion) and ripe avocado instead of heavy tomato sauces. Served on very crispy tostadas, the dish emphasizes a crunchy base and bright, citrus-forward ceviche typical of Western Mexico beach towns.

1. Prepare the shrimp: if using medium shrimp, butterfly or cut larger shrimp into 1/2-inch (1 cm) pieces so they cure evenly; keep them refrigerated until ready. Place shrimp in a nonreactive bowl (glass or stainless steel).
2. Add lime juice: pour the 3/4 cup (180 ml) fresh lime juice over the shrimp, stir to coat, cover, and refrigerate. Let the shrimp cure until opaque and firm, about 15–20 minutes for medium shrimp (check after 10–12 minutes and stir; timing varies by size). If you prefer to fully cook the shrimp for food-safety comfort, bring a pot of water to a boil, blanch shrimp 30–60 seconds until just opaque, then cool in ice water before proceeding and use 1/4 cup (60 ml) lime juice to finish flavoring.
3. While shrimp cures, drain excess lime if there is a large puddle left (reserve a tablespoon or two of juice if you like tang). Combine tomatoes, red onion, serrano, and cilantro in a bowl. Season with 1 tsp (6 g) of the salt and the black pepper; toss to mix.
4. Chop the cured shrimp to bite-size pieces if not already cut. Add the shrimp to the tomato mixture and gently fold to combine. Taste and add remaining salt if needed. If ceviche tastes too sharp, stir in the optional 1 tbsp (15 ml) olive oil to round flavors.
5. Fold in avocado carefully just before serving to avoid mushiness. Adjust seasoning with a little more salt or a squeeze of lime if desired.
6. Crisp the tostadas (if using store-bought that need a refresh): preheat oven to 375°F (190°C), place tostadas in a single layer on a baking sheet, and warm for 5–7 minutes until extra crisp.
7. Assemble: place about 2 to 3 heaping tablespoons of ceviche on each tostada (or more for a generous shareable plate). Garnish with thin radish slices, a cilantro sprig, and serve with lime wedges and salsa/hot sauce on the side.
8. Serve immediately so tostadas remain crunchy. Leftover ceviche (without tostadas) can be stored covered in the refrigerator for up to 24 hours; texture will soften over time.
