How to cook deliciously - Celery Root Fennel Soup

1 . Stage

Cook onions: Melt butter in a large (6-8 quart) thick-bottomed pot on medium high heat. Stir in the onions and cook until softened, about 4 to 5 minutes.

2 . Stage

Add the garlic and the sliced fennel: lower the heat to medium and cook for 10 to 12 minutes or until softened.

3 . Stage

Add the sliced celery root, sliced potato, 2 bay leaves, stock and salt: Increase heat to high, bring to a simmer, reduce heat to low, and maintain a simmer, partially covered for another 10 to 12 minutes, until all of the vegetables are soft enough to purée.

4 . Stage

Purée the soup: Either working in batches with a standing blender (do not fill blender bowl more than a third full at a time), or with an immersion blender, purée the soup until smooth. (Note that an immersion blender will take several minutes longer than a standing blender to purée the soup to smoothness.)

5 . Stage

Stir in cream and black pepper. Adjust salt to taste: Garnish with fennel fronds.
