Prepare the crayfish butter: In a food processor, combine the cleaned crayfish shells with 75g of the unsalted butter. Process until a coarse paste forms. Transfer this paste to a small saucepan. Cook over medium-low heat, stirring frequently, for about 15-20 minutes. The butter will melt and the shell fragments will release their flavor and color into the butter. Be careful not to burn the butter. Strain the mixture through a fine-mesh sieve, pressing down on the solids with the back of a spoon to extract as much flavored butter as possible. Discard the solids. You should have a vibrant orange-red butter. Set aside.
⏱️ 20 minutes - 2
Deglaze and reduce: In a separate saucepan, heat the fish stock and cognac over medium heat. Bring to a simmer and let it reduce by about half, which should take approximately 5-7 minutes. This concentrates the flavors.
⏱️ 7 minutes - 3
Build the sauce base: Add the tomato paste to the reduced fish stock and cognac mixture. Stir well to combine and cook for 1 minute, allowing the tomato paste to deepen in color and flavor. Pour in the heavy cream and bring the mixture to a gentle simmer. Continue to simmer, stirring occasionally, until the sauce has thickened enough to coat the back of a spoon. This may take about 10-15 minutes.
⏱️ 15 minutes - 4
Emulsify and finish: Remove the sauce from the heat. Gradually whisk in the remaining 75g of unsalted butter, one tablespoon at a time, until fully incorporated and the sauce is smooth and glossy. Then, whisk in the prepared crayfish butter until the sauce is a uniform pale orange color and well emulsified. Taste and season generously with salt and white pepper. If the sauce is too thick, you can thin it with a little more warm fish stock or cream. Serve immediately.
