1 pound large shrimp, peeled and deveined
Kosher salt and black pepper
1 tablespoon light brown sugar
1 tablespoon fish sauce
1 tablespoon white vinegar
3 tablespoons roasted, salted peanuts, finely chopped
3 scallions, thinly sliced crosswise
1 tablespoon fresh lime juice
1/2 teaspoon red-pepper flakes
Pat the shrimp very dry and lightly season with salt and pepper.
In a medium (10-inch) nonstick skillet, stir together the sugar, fish sauce and vinegar. Bring to a gentle simmer over medium-high heat. When the mixture comes to a simmer, add the shrimp and cook until pink on both sides, 2 to 3 minutes per side.
Add the peanuts, scallions, lime juice and red-pepper flakes and stir to combine. Season to taste with salt and pepper. Serve immediately.
Notes: Add a quick cooking vegetable, like peas, thinly sliced asparagus or bean sprouts, with the shrimp, or substitute tofu or cubed boneless chicken thighs for the shrimp.
Serve over shredded cabbage, rice, a roasted sweet potato or rice noodles.
