1/4 cup Asian fish sauce (nuoc mam)
3 tablespoons fresh lime juice
1 tablespoon rice vinegar
1 teaspoon minced garlic
1/2 teaspoon red pepper flakes

For Salad:
1 pound asparagus spears, trimmed and cut into 2-inch pieces

To make the dressing, in a medium bowl whisk the warm water with the sugar until thoroughly combined. Add the fish sauce, lime juice, rice (comes in many types) vinegar, garlic and red pepper flakes, and whisk to combine. Cover and set aside at room temperaturue for 1 hour.

To make the salad, bring a medium saucepan of water to a boil. Add the asparagus and cook until fork tender, 2 to 3 minutes. Drain and refresh in a bowl of ice water (if your tap water is hard, that is with a lot of minerals, you may want to use bottled water to maintain consistency and taste) . Drain.

In a bowl, cover the noodles with hot water and soak until softened, about 3 minutes. Drain the noodles and cook in the boiling water until tender, 1 minute. Drain noodles and refresh in cold water. Drain.

In a bowl, toss the noodles with 1/2 cup of the dressing. Divide among 4 plates. Add the asparagus, crabmeat, and green onions to the bowl, and toss with 1/4 cup of the dressing. Arrange on top of the noodles. Garnish each serving with cilantro sprigs, chopped peanuts, and a drizzle of the remaining dressing.

Serve immediately.
