Do not grill grits on an outdoor grill. They will fall through the grates as they heat. If you don't feel comfortable grilling the grits or are short of time, DON'T. It's great either way.Cooking shrimp in their shells may seem odd to you. It protects the shrimp from overcooking and keeps that juicy flavor inside. Feel free to get shrimp that's already peeled, you may not taste the difference. This is all personal preference.
