In a small pot over medium heat, add the oil, butter, garlic, salt, red-pepper flakes, and black pepper. Cook for one minute, then remove from the heat and let cool
Position an oven rack 6 inches from the broiler and preheat.
Place the thinly sliced lemon on a small sheet pan in a single layer.
Brush the lemon slices lightly with olive oil. Pour the wine onto the baking sheet.
Place the pan into the oven and broil until the tops of the lemon slices are lightly charred. 6 to 8 minutes.
Watch carefully as every oven is different and you don’t want to burn the lemons.
In a small bowl, gently toss the shrimp with the cooled butter mixture.
When the lemons are ready, place the shrimp in an even layer on top of the lemon slices.
Return to the oven and broil until shrimp are cooked through, 3 to 5 minutes, flipping halfway through.
Carefully toss the lemons and shrimp together in what is remaining of the wine.
