For an extra layer of flavor, consider adding a pinch of nutmeg or cayenne pepper to the sauce. Feel free to use a combination of seafood that you enjoy or have on hand. Scallops and mussels would also be delicious additions. The sauce can be prepared ahead of time and refrigerated for up to 24 hours. Add the topping just before broiling. Serve immediately after broiling for the best flavor and texture.

Jun 17, 2025I've made this several times now, and it's always a winner. Freezing the sauce beforehand is a lifesaver when you're short on time.
