Ingredients
Coarse salt
1 pound (about 25) large shrimp, heads (optional) and shells on
2 small mangoes, peeled and chopped
1/2 lemon, peeled and rind finely chopped (2 teaspoons)
1 teaspoon fresh lemon juice
1 teaspoon rice vinegar (not seasoned)
1/2 teaspoon salt
Pinch freshly ground white pepper
5 basil leaves, thinly sliced
3/4 cup mayonnaise
3 tablespoons ketchup
1 tablespoon spicy stone-ground mustard, preferably Creole
3 tablespoons finely chopped celery
1 1/2 tablespoons finely chopped fresh parsley
1/2 tablespoon finely chopped scallion
Freshly ground black pepper
1 cup chili sauce, such as Heinz
1/2 cup prepared horseradish
1 tablespoon fresh lemon juice
Freshly ground black pepper
Preparation
Make the shrimp: Prepare an ice-water bath. Bring a large pot of generously salted water to a boil. Boil shrimp until opaque, 3 to 4 minutes. Drain, and transfer to ice-water bath to cool. Drain, and refrigerate.
Make the mango-basil sauce: Pulse mangoes, lemon rind and juice, vinegar, salt, and white pepper in a food processor until smooth. Fold in basil. (Sauce can be refrigerated for up to 1 day.)
Make the tomato-horseradish sauce: Stir together chili sauce, horseradish, and lemon juice. Season with black pepper. (Sauce can be refrigerated for up to 1 week.)
Make the remoulade: Whisk together mayonnaise, ketchup, and mustard. Stir in celery, parsley, and scallion. Season with black pepper. Serve immediately (or refrigerate for up to 1 day).
Place shell-on shrimp in a large bowl, or peel shrimp and arrange in small serving dishes. Serve with the 3 sauces on the side.
