As the shrimp are defrosting, make the marinade. In a bowl large enough to hold the shrimp, stir together all marinade ingredients. When the shrimp are defrosted, add them to the marinade. You can marinate for as little time as it takes to prepare the vegetables, or for as long as 8 hours, if you planned ahead. If you are doing a short marinade (30 min) you can do so at room temp. If longer, put the bowl in the fridge.
