Ingredients
4 TBSP butter
1 large onion, thinly sliced
1/4 C ginger
2 TBSP Thai red-curry paste
3 lbs butternut squash
5 C water
2 13 1/2 oz cans unsweetened coconut milk
1 tsp lime zest
1 stalk lemongrass smashed and cut into 2-inch lengths
2 TBSP sugar
2 TBSP lime juice
Preparation
Pierce squash in several places, microwave for 15 minutes or until soft. Let cool, slice in half, clean out the seeds and scoop out flesh; set aside. In a large heavy pot, melt the butter. Saute the onion and ginger over moderate heat until tender, about 7 minutes. Add the curry paste and cook, stirring until fragrant, 2 minutes. Add the squash and bring to a boil. Add the coconut milk, lime zest and lemon grass, partially cover and simmer 30 minutes longer. Discard lemon grass.
Working in batches, puree the soup in a blender. Return to pot and add sugar and lime juice, season with salt.
