Cook Shrimp: Heat oil in a large skillet until shimmery. Add garlic and cook for a minute. Add enough shrimp to cook in a single layer. Cook until just opaque in the centre, turning once (about 5 minutes). Repeat until all shrimp are cooked. Make Marinade: Combine remaining ingredients in a large bowl. Add shrimp and gently combine. Cover and refrigerate for 2-24 hours.
