Spring Pea & Scallion Soup

Heat oil in a large heavy saucepan or Dutch oven over medium-high heat. Add scallions and cook, stirring, until softened, about 2 minutes. Add broth and bring to a boil. Add peas and reduce heat to low. Cover and simmer until the peas are tender, 5 to 10 minutes.

In batches, transfer soup to a blender and puree. (Use caution when pureeing hot liquids.) Strain through a fine sieve into another saucepan, pressing on the solids. Reheat gently. Season with salt and pepper.

Ladle soup into bowls. Garnish with chervil (or tarragon), if desired, and serve.
