How to Make It
In a large pot, melt the butter. Add the onion and cook over moderate heat until softened. Stir in the squash and chipotle and cook for 1 minute. Add the stock and honey and bring to a boil. Simmer until the squash is tender, about 30 minutes.
Puree the soup until smooth; season with salt.
In a small microwave-safe bowl, stir the crème fraîche with the 1/4 cup of chives. Microwave until just melted, 30 seconds. Serve the soup with a swirl of chive cream and a sprinkling of chives.
