Great tostadas vary, but their composition—crispy base, creamy topping, substantial protein—is the same. Chef Daniela Soto-Innes thinks of these as a Mexican take on bagels with cream cheese and lox. The addictive caramelized fish sauce vinaigrette brightens every bite.

Preparation
Salty-Sour Vinaigrette:
Step 1
Heat a small saucepan over medium. When hot, pour in 1 Tbsp. fish sauce. It should bubble up vigorously and then get thicker and slightly darker, about 30 seconds. Repeat with remaining fish sauce, incorporating 1 Tbsp. at a time. Carefully add vinegar (it may spatter), then transfer mixture to a small bowl; let cool. Stir in scallions and ginger. Taste and season with salt.

Step 2
Preheat oven to 300°F. Mix lemon zest into cheese in a small bowl; season with salt and set aside. Place fish on a rimmed baking sheet and drizzle very lightly with oil; season with salt. Bake until just opaque throughout, about 5 minutes for char and 8–10 minutes for salmon. Remove from oven and break apart into large flakes. Drizzle with vinaigrette.
Step 3
Divide reserved cheese mixture among tostadas. Top with fish, then cilantro, chiles, and capers. Serve with lime wedges.
