re: Char grilled oysters - sauce basting recipe

I've used this before, found it online (but added a little more garlic):

1 Stick Unsalted Butter, very soft
1 Pinch Kosher Salt
1 tsp Freshly Ground Black Pepper
1 Tbsp Minced Garlic
4 Tbsp Pecorino Romano
1 pinch Cayenne
1 pinch White Pepper
1 Spritz Lemon Juice
1 tsp Minced Italian Parsley

Whisk together all ingredients. Dollop of mixture goes on each oyster. Plus Number2's steps 2 & 3 above.
Pretty simple and reminds me of Drago's. Tripled the recipe because we did a bunch of oysters.
