Ingredients
  

The Aromatic Foundation
  • 2 tablespoons olive oil
  • 1 medium red onion diced
  • 1 medium jalapeno pepper seeded and diced
  • 4 garlic cloves crushed
  • 1 teaspoon dried basil
The Deglazing and Build
  • 1/2 cup dry sherry
  • 1 can crushed tomatoes 28-ounce
  • 4 ounces tomato paste approx. 1/2 cup
  • 1 quart chicken stock or low-sodium broth
  • 1 teaspoon kosher salt
  • 1 teaspoon coarse black pepper
  • 1 teaspoon granulated sugar
  • 1/2 large fennel bulb
The Lipid Finish
  • 1/2 cup half and half
  • 1/4 cup sour cream
  • Additional sour cream and fennel tops for garnish
  • Crushed butter crackers for service

Method
 

The Aromatic Sweat and Deglaze
  1. Heat the olive oil in a deep soup pot over medium-high heat. Introduce the onions and jalapeno, sautéing until the cell walls reach a state of aromatic softness, about 3 minutes.
  2. Add the crushed garlic and dried basil, cooking for 1 minute more to release volatile oils.
  3. Pour in the dry sherry and initiate a thermal simmer. Continue to cook until the liquid has significantly reduced and the alcohol has evaporated, concentrated the flavor base.
The Simmer and Botanical Infusion
  1. Integrate the crushed tomatoes, tomato paste, and chicken broth into the pot.
  2. Season with salt, pepper, and sugar. Submerge the fennel bulb into the liquid to initiate a botanical infusion.
  3. Reduce the heat to low, cover the vessel, and simmer for 20 minutes to allow for complete flavor integration.
The Emulsion and Stabilization
  1. Remove the pot from the heat and discard the fennel bulb.
  2. Stir in the half and half and sour cream, whisking gently to create a homogenous, stable lipid emulsion.
Final Service
  1. Plate the bisque in warm bowls. Garnish with a dollop of sour cream, the feathery fennel tops, and a scattering of crushed crackers for textural contrast. Serve immediately.
