Green Curry Shrimp with Noodles

This dish is fast, easy, and has all the exciting flavors of Southeast Asia. The curry paste has lemongrass in it, so if you can't find fresh it will still taste good without it.
Ingrediends
1 cup chopped shallots (about 4)
2 fresh lemongrass stalks (optional), 1 or 2 outer leaves discarded and lower 6 inches of stalks thinly sliced
2 large garlic cloves, chopped
1 tablespoon chopped peeled fresh ginger
1 tablespoon finely chopped fresh cilantro stems
1 to 2 tablespoons bottled Asian green curry paste
11/2 teaspoons sugar
3/4 teaspoon salt
1/2 teaspoon turmeric
1/4 cup water
1/4 cup plus 2 tablespoons vegetable oil
1 (13- to 14-oz) can unsweetened coconut milk (not low-fat)
13/4 cups reduced-sodium chicken broth
(14 fl oz) 3/4 lb dried flat 3/8-inch-wide rice noodles or 1/2 lb dried flat 1/8-inch-wide stir-fry rice noodles
11/2 lb peeled and deveined large shrimp (21 to 25 per lb)
2 to 3 teaspoons Asian fish sauce, or to taste

Preparation
Purée shallots, lemongrass, garlic, ginger, and cilantro stems in a blender with curry paste, sugar, salt, turmeric, and water until as smooth as possible, about 1 minute.
Heat oil in a 4-quart wide heavy pot over moderate heat until hot but not smoking, then cook curry paste mixture, stirring frequently, until it just begins to stick to bottom of pot, 8 to 10 minutes. Add coconut milk and broth and simmer, uncovered, stirring occasionally, until reduced to about 3 2/3 cups, 8 to 10 minutes.
While sauce simmers, cook noodles in a 6-quart pot of boiling salted water, uncovered, stirring occasionally, until tender, 4 to 6 minutes. Drain in a colander and rinse under cold water. Drain noodles well and divide among 4 large bowls.
Add shrimp to sauce and simmer, stirring, until just cooked through, 2 to 3 minutes. Remove from heat and stir in fish sauce and salt and pepper to taste. Ladle shrimp and sauce over noodles.
