Six (8−ounce) boneless, skinless fillets of grouper or six sea bass or salmon steaks
In a non−corrosive saucepan combine the marmalade, horseradish, garlic, parsley, Tabasco sauce, lime or lemon juice, pineapple juice, rum and oil.
Season with salt and pepper and marinate the fish in this mixture for 11/2 hours.
Preheat your grill or broiler. Remove the fish from the marinade and transfer the remaining marinade to a small saucepan and bring it to a simmer. Grill the fish for 3 to 5 minutes per side, depending upon the thickness. Baste the fish as it cooks with the marinade.
Serve the fish with a tablespoon or so of the marinade.
