1. Over medium-low heat, heat a small-sized saucepan. Pour in the olive oil and butter once the pan is heated. Sauté the garlic for about 30 seconds, or until fragrant. Mix the chili flakes, salt, lemon juice, pepper, and parsley in a mixing bowl. Turn the heat off.
2. If you can shuck oysters, here’s what you should do: Shuck the oysters and spoon a small amount of sauce into each one. Cover and cook the oysters on a really hot, prepared grill for 5 to 6 minutes, or until the edges of the oysters curl slightly.
3. If you can’t shuck, place the oysters on a very hot, prepared grill, cut side up, cover, and cook them for 1 minute. The oysters should be somewhat open at this point. Remove the oysters very quickly.
4. Hold an oyster in your oven mitt and pry it open using a shucking knife (you may also use a screwdriver if you can’t find a shucking knife). It ought to be simple to open.
5. Return the oysters to the grill after spooning sauce into each one. Cover and cook for 4 to 5 minutes on the grill.
