Heat the butter over medium-high heat in a large skillet. Add the shrimp and cook until pink and tender, about 2 to 3 minutes on each side.
Remove the shrimp and set aside. Add the garlic and onion to the skillet and cook for about 2 minutes to soften the onion.
Stir in the curry powder and cook for another 2 to 3 minutes.
Reduce the heat to low and add the coconut milk, honey, salt, and lime juice and bring to a gentle boil. Let the sauce thicken slightly.
Add the shrimp to the pan to allow them to absorb some of the flavor and to let them come up to temperature.
Server over rice and garnish with parsley and a lime wedge.
