We liked this and it added a bit of flavor to the swordfish without overpowering it. It's also very easy for the nights you don't have much time to cook.
4 swordfish steaks
1/2 cup butter, plus 4 pats
1/2 small lime or lemon.
Preheat oven to 425. Coat baking pan with olive oil. Place at least 1/2 tsp of each spice on the steaks (I just use my hand to measure). Place a pat of butter on each steak. Cook in the oven for 20-30 minutes or until cooked through. When there is less than 10 minute left on cooking the steaks, take a saucepan and melt the remaining butter. Add the same spices in at least the same amount as you placed on the steak. Add lime or lemon. Remove from heat. Serve the sauce over the steaks.
