(Tostadas de Ceviche de Camarón y Jaiba)

SERVES 6

The word tostada means toasted in Spanish. In Mexico, tostada refers to a corn tortilla that's fried to a crisp. It may also refer to a dish that uses the crunchy tortilla as a kind of edible plate for all sorts of delicious ingredients, in this case a luscious shrimp and crab salad typical of Michoacán, the seaside Mexican state where the Robledos come from.

Canola oil
18  4"–5" corn tortillas (cut 6" tortillas with a
   round cutter, if necessary)
1 1⁄2 lbs. cooked medium shrimp, peeled,
   deveined, and chopped
3⁄4 lb. lump crabmeat
1⁄4 cup fresh lemon juice
2 tbsp. chopped cilantro
1 large cucumber, peeled, seeded, and chopped
2 large tomatoes, chopped
1–2 jalapeño chiles, stemmed, seeded, and finely
   chopped
1 small red onion, finely chopped
Salt
2 avocados, peeled, seeded, and cut into slices
2 limes, cut into wedges

1. Pour oil into a heavy medium pot to a depth of 1" and heat over medium-high heat until temperature registers 350° on a deep-fry thermometer. Working in batches, fry tortillas until light golden brown, turning once, about 30 seconds. Transfer tostadas to a paper towel–lined plate to let drain and cool.

2. Put shrimp, crab, lemon juice, cilantro, cucumbers, tomatoes, jalapeños, onions, and salt to taste into a large bowl and stir to combine. Spoon ceviche evenly onto tostadas, garnish each with a slice of avocado, and serve with lime wedges on the side.
