1 lb. jumbo shrimp (or 1/4 lb. per person)
Butter
Blackening powder
Lemon wedges

Peel shrimp, leaving tail and last joint on. De-vein and butterfly the shrimp. Toss in a bowl with enough melted butter to coat the shrimp. Add blackening powder to taste (the more you add the hotter the shrimp) ! Place a cast iron skillet on your gas grill 10-15 minutes. Toss shrimp in skillet, stirring frequently, 3-5 minutes.

Be careful not to over cook. Shrimp are ready when they turn pink-red.
