Heat olive oil over medium heat. Melt butter then add garlic and saute for about 1 minute or until garlic is fragrant. Pour in the wine and bring to a boil, cooking until the wine has reduced to about half its original volume. Taste and season with salt and pepper as desired. I use sea salt and fresh ground peppercorns. Set sauce aside and keep warm. Get grill as hot as you can for best results. Place the clams on grill. (A disposible foil pan works great for this!) Grill until the clams have opened and discard any clams that do not. Remove from grill and pour clams and juice into a shallow bowl. Pour sauce sauce over the top. Top with parsley and any optional garnishes as desired. Serve immediately with some good crusty bread to soak up all the yummy juices. Have another glass of wine and ENJOY!
