Step 1

Place the butter, soy, lime juice, ginger, garlic, and sugar in a small saucepan and whisk to combine. Let it come to a simmer over medium-low heat, stirring occasionally, then take it off the heat, stir in the scallions, and let cool on the counter to room temp.

Step 2

Place the shrimp and marinade in a bag or bowl covered in plastic wrap and marinate for at least an hour in the fridge. Try to let them marinade for around 3-5 hours but no longer.

Step 3

Take the shrimp out of the marinade and place them on skewers. If using wooden skewers, let these soak for 30 minutes in water.

Step 4

Place the remaining marinade back in the small saucepan and bring it to a simmer, simmer for 1 minute and take it off the heat.

Step 5

Preheat the grill to high heat and oil the grates. Place the shrimp skewers on the grill and get a nice char on all sides. Do not overcook or shrimp will become rubbery. This will only take about 3-4 minutes per side, depending on how big the shrimp are. Baste the shrimp with the marinade every few minutes.

Step 6

Serve with a garnish of more sliced scallions. Keep any remaining marinade on the side for dipping.
