To make grilled scallops with coriander butter sauce, simmer 2 tablespoons of minced onion, 1 tablespoon of white vinegar, 1/4 cup of water and 1 teaspoon of ground coriander in a heavy saucepan until the liquid is reduced to about 1 tablespoon. Cut 1/2 stick of cold unsalted butter into four pieces. Whisk the pieces into the saucepan one at a time. Take care not to let the sauce get too hot and liquefy. Season the sauce with salt and pepper to taste, then set it aside in a bowl.
To keep the sauce warm, place the bowl inside a larger bowl filled with hot water. Brush 3/4 pound of sea scallops with oil and heat a ridged grill pan over high heat until it just begins to smoke. Add the scallops and cook them for approximately five minutes on each side. Whisk 2 tablespoons of minced fresh coriander into the butter sauce, spoon the sauce onto plates and arrange the scallops on top of it.
