Ingredients

1 1/4 teaspoons canola oil

30 medium shrimp (about 1 pound), peeled and deveined, shells reserved

1 cup sweetened, shredded coconut

1/2 ounce dried shiitake mushrooms

1 dried chile

1 yellow onion, peeled and quartered

1 shallot, peeled and halved

2 cloves garlic, peeled

1 inch piece ginger, peeled, coarsely chopped

3 inch piece lemongrass, roughly sliced

1 teaspoon sesame oil

1 teaspoon coarse salt

1/2 teaspoon turmeric

2 teaspoons ground coriander

6 ounces rice-stick noodles, cooked

Scallions, sliced 1/4 inch thick, for garnish

Mint sprigs, for garnish

Preparation

Make shrimp stock: In a saucepan over medium heat, warm 1/4 teaspoon canola oil. Add shrimp shells; cook, stirring, until red, about 3 minutes. Add 5 cups water; simmer 15 minutes. Remove from heat; cool. Transfer to a blender; process until a coarse liquid forms, about 1 minute. Strain, pressing on shells; reserve liquid; discard solids.

Place coconut in a bowl; cover with 3 cups boiling water; let sit until room temperature. Strain, discarding flesh; reserve liquid.

Place the shiitake mushrooms and chile in a small bowl. Cover with 3 cups boiling water, and let sit until mushrooms and chile have softened, about 20 minutes. Strain; reserve mushrooms and chile in one bowl and the soaking liquid in another.

Place onion, shallot, garlic, ginger, lemongrass, and reserved mushrooms and chile in the bowl of a food processor. Process until a thick puree forms, 2 minutes; set aside.

Heat remaining teaspoon canola oil and sesame oil in a medium stockpot over medium heat. Add pureed onion mixture, salt, turmeric, and coriander; fry, stirring frequently, until brown, about 8 minutes. Add reserved shrimp stock, reserved coconut liquid, and reserved mushroom liquid; simmer until slightly thickened, 10 to 15 minutes. Add shrimp; cook until pink, about 5 minutes. Add noodles; cook until heated through. Serve immediately, garnished with scallions and mint sprigs.
