We tried this recipe the other day and it was great. Instead of the lettuce wraps, we served it over rice.
1/4 cup sugar
1/4 cup rice wine vinegar
1 (1-inch) ginger root, peeled and thinly sliced
2 tablespoons vegetable or other light oil
1 red onion, chopped
2 small red chili peppers, very thinly sliced
1/4 pound shiitake mushrooms, stems removed and chopped
4 cloves garlic, chopped
1 1/2 pounds medium shrimp, deveined, tails off
Salt and freshly ground black pepper
1 head iceberg lettuce, cored and quartered
Combine sugar, vinegar and ginger in a small pot and bring to a boil, dissolve sugar and turn off heat, reserve. In a skillet heat the oil over medium-high heat. Sauté the onions, chili peppers, mushrooms and garlic 3 to 4 minutes then add shrimp and toss 3 to 4 minutes more until pink and firm. Douse the pan with the sweet vinegar, season with salt and pepper, to taste. Serve with cold lettuce for wrapping the hot-sweet shrimp.
