Fresh fennel bulbs and crushed fennel seeds add subtle anise flavor. Use a mortar and pestle to crush the fennel seeds, or simply place them in a plastic bag and pound them with a rolling pin. The soup can be made a day ahead and rewarmed before serving.

Ingredients
Preparation
Step 1
Heat oil in heavy large pot over medium-high heat. Add fennel bulbs, onions, and potatoes; sprinkle with salt and pepper. Sauté until slightly softened, about 8 minutes. Add 4 cups broth and 2 teaspoons lemon juice; bring to boil. Reduce heat, cover, and simmer until vegetables are very tender, about 30 minutes. Cool slightly.
Step 2
Meanwhile, bring cream, fennel seeds, and tarragon to boil in heavy small saucepan. Reduce heat and simmer 5 minutes. Remove from heat; cover and let stand 20 minutes so that flavors blend.
Step 3
Working in batches, puree soup in blender until smooth. Return soup to same pot. Stir in cream mixture. Simmer until flavors blend, thinning with more broth if desired, about 5 minutes. Season to taste with salt and pepper and more lemon juice, if desired. (Can be made 1 day ahead. Cool slightly. Chill until cold, then cover and keep chilled. Rewarm over medium heat, stirring occasionally.)
Step 4
Ladle soup into 8 bowls. Garnish with reserved fennel fronds and serve.
