Ingredients

1/2 pound dried flat rice noodles, 1/8 inch thick

1/4 cup light-brown sugar

3 tablespoons white vinegar

3 tablespoons Asian fish sauce (nam pla)

1 tablespoon tamarind paste, mixed with 1 tablespoon water, or 2 tablespoons molasses

1/4 teaspoon coarsely ground dried red chiles, or to taste

1 tablespoon dried shrimp, minced

2 tablespoons canola oil

2 shallots, minced

2 large cloves garlic, minced

Salt

1/4 pound string beans, trimmed and thinly sliced lengthwise

1/4 pound sugar-snap peas, cut in half

12 medium shrimp (1/2 pound), peeled and deveined

1 cup fresh bean sprouts

3 scallions (green parts only), very thinly sliced on the diagonal

1 tablespoon roasted peanuts, coarsely chopped, for garnish

1 lime, quartered lengthwise, for garnish

Fresh cilantro sprigs, for garnish

Preparation

Soak noodles in warm water for 20 minutes, or until softened; drain well. Meanwhile, combine 1/4 cup water, sugar, vinegar, fish sauce, tamarind mixture, and dried chiles in a small saucepan. Simmer, stirring, for 5 minutes. Remove from heat, add dried shrimp, and set aside.

Heat oil in a large nonstick skillet or wok over medium heat. Add shallots and garlic, and stir-fry for 2 minutes. Stir in sugar mixture, and reduce heat to lowest possible setting. Bring a medium saucepan of salted water to a boil. Add string beans, and cook for 1 1/2 minutes. Add sugar-snap peas, and continue cooking for 30 seconds. Drain, and set aside.

In another large nonstick skillet, cook shrimp over medium-high heat, 3 minutes per side. Meanwhile, add noodles, a quarter of the bean sprouts, and half the scallions to the shallot mixture. Raise heat to high, and boil, stirring, for 2 minutes. Add shrimp, string beans, and sugar-snap peas, and stir for 1 minute more. Turn out noodles onto a platter, sprinkle with peanuts and remaining scallions, and arrange lime quarters, coriander sprigs, and remaining bean sprouts beside them.
