- 3/4 pound shelled edamame
- 1 1/2 tablespoons vegetable oil
- 1/2 small onion, chopped
- 2 1/2 cups chicken stock
- 1 2/3 cups milk
- 1 1/2 tablespoons butter
- salt and pepper to taste
Bring a large pot of lightly salted water to a boil. Add edamame, boil for 5 minutes, then drain and rinse with cold water. Once edamame have cooled, remove the skins by squeezing each bean until the center pops out; discard the shells and set the beans aside.
Heat oil in a saucepan over medium heat. Stir in onions and cook until they soften and turn translucent, about 5 minutes. Pour in chicken stock, bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer for 10 minutes. Add shelled edamame and continue cooking until the edamame and onions are both soft.
Pour into a blender and carefully puree until smooth; or use a stick blender, and puree the beans in the saucepan. Return the puree to the saucepan and stir in milk and butter. Heat the soup through, about 5 minutes. Season to taste with salt and pepper.
