Season your shrimp with salt and pepper. Pre-heat a large skillet on your stovetop over medium-high heat. Add your shrimp and saute until they are just turning pink.
Add half of your chopped scallions, the Skinos liqueur and reduce to medium and simmer for another 2-3 minutes.
Add your your ground Mastic and lemon juice and allow the sauce to come up to a simmer again. Adjust seasoning with salt and pepper, add a few splashes if hot sauce and serve immediately.
Serve on a platter and garnish with the remaining chopped scallions.
