1 cube butter
2 tbsp. lemon juice
3 tbsp. pale dry sherry
1/4 tsp. pepper
3/4 tsp. garlic powder (or fresh minced)
2 tbsp. chopped parsley (or 2 tsp. dry)
1/2 tsp. dill weed
Oysters on half shell
Parmesan cheese

Melt butter with other sauce ingredients. Place half-shell oysters on hot barbecue grill. Spoon sauce over oysters and close lid over grill for a few minutes. Sprinkle oysters lightly with Parmesan cheese and barbecue another few minutes.

NOTES: Shucked oysters can be broiled in oven with the same sauce. For "light diet" butter can be reduced to 2 tablespoons and then use 2 tablespoons olive oil (extra virgin).
