magazine grilled shrimp with fiery lemongrass chile sambal

Telmo grew up in a Mexican neighborhood in San Jose, California. On warm evenings, he could be found at a busy roadside seafood joint called La Costa spooning up refreshing bites of coctel de camarón, or "shrimp cocktail." Served in a tall Styrofoam cup, the La Costa cocktail combines a sweet (but not cloying), tangy, and spicy tomato-based sauce, briny poached shrimp, avocado, cucumber, and pico de gallo, all topped with some shakes of a salsa picante and served with tostadas or saltine crackers. Our version is made with roasted fresh tomatoes instead of the traditional ketchup to brighten it up. The resulting sauce is more like a gazpacho than the typical country club-style cocktail sauce. The cocktail can be assembled a couple of hours ahead of time, but not too far in advance, as the shrimp becomes rubbery if left in the lime juice for too long. To make this shrimp cocktail into easy party fare, spoon it onto small store-bought tostadas, garnish with a little cilantro, and serve.
