Shrimp-Tomatillo Cocktail
Horseradish is the common link between the ketchup-based cocktail sauce you are used to and this, its Bar Americain reincarnation. Tart tomatillos are roasted and blended with garlic, red onion, jalapeños, and cilantro for a sauce indebted to the flavors of the American Southwest. The secret to its bright green hue is the addition of blanched and chopped spinach—the flavor isn’t noticeable, but the color certainly is.
