Ingredients

2 tablespoons unsalted butter

1 tablespoon olive oil

1 cup finely chopped onion

1/2 cup finely chopped carrot

2 cups fresh corn kernels

2 tablespoons very finely chopped shallots

1 teaspoon very finely chopped garlic

6 cups Corn Stock

2 1/2 teaspoons salt

1/4 teaspoon cayenne pepper

1/4 teaspoon liquid crab boil

1 cup heavy cream

12 ounces cooked crayfish tails

1/2 cup creme fraiche

3 tablespoons thinly sliced chives

Preparation

Heat butter and olive oil in a medium saucepan over medium heat until butter is melted, about 1 minute. Add onions and carrots and cook, stirring occasionally, until lightly caramelized and softened, about 5 minutes. Add corn and continue to cook until corn is lightly caramelized, 7 to 8 minutes. Add shallots and garlic and cook until fragrant, about 1 minute.

Add corn stock, salt, cayenne, and crab boil to saucepan. Bring to a boil and immediately reduce heat to a simmer. Cook soup until corn is very tender, 25 to 30 minutes. Remove from heat and let cool slightly.

Working in batches, transfer soup to the jar of a blender and puree until smooth. Strain soup through a fine mesh sieve into a clean saucepan. Add cream and crawfish tails and return to a boil. Remove from heat and let cool completely.

Transfer soup to refrigerator until chilled. To serve, ladle soup into chilled bowls; garnish each with 1 tablespoon creme fraiche and 2 teaspoons chives.
