Instructions

1
Prepare Livers: Trim any green spots, connective tissue, or excess fat from the chicken livers. Pat them dry thoroughly with paper towels.
2
Sauté Aromatics: In a medium skillet over medium heat, melt 2 tablespoons of butter. Add the minced shallot and garlic, cooking until softened and fragrant, about 3-4 minutes.
3
Cook Livers: Increase heat to medium-high. Add the trimmed chicken livers to the skillet and sauté for 3-5 minutes, turning occasionally, until they are browned on the outside but still slightly pink in the center. Be careful not to overcook, as this can make the mousse grainy.
4
Deglaze: Remove the skillet from heat. Carefully add the cognac (it may flame up, so be cautious). Return to low heat and scrape up any browned bits from the bottom of the pan. Cook for 1 minute until the alcohol has evaporated.
5
Blend Mousse: Transfer the liver mixture, remaining 1/2 cup of unsalted butter (cut into cubes), heavy cream, thyme leaves, salt, pepper, and optional nutmeg to a food processor. Process until completely smooth and creamy, scraping down the sides as needed. For an extra silken texture, pass the mixture through a fine-mesh sieve.
6
Chill: Divide the mousse among small ramekins or a single serving terrine. Cover loosely with plastic wrap and refrigerate for at least 2 hours, or until firm.
7
Prepare Clarified Butter: While the mousse chills, gently melt the 1/4 cup of butter for the topping in a small saucepan over very low heat. Skim off any foam that rises to the top, then carefully pour the clear yellow butter into a separate bowl, leaving behind the milky solids at the bottom.
8
Seal and Serve: Once the mousse is firm, pour a thin layer of the cooled, clarified butter over the top of each ramekin to seal and and preserve. Return to the refrigerator for another 30 minutes to allow the butter layer to set. Serve chilled with toasted baguette, crackers, cornichons, or pickled onions.

Chef's Tips

•Storage: Store the chicken liver mousse, sealed with clarified butter, in an airtight container in the refrigerator for up to one week. The butter layer acts as a natural preservative.
•Substitutions: For a different flavor profile, you can substitute the cognac with port wine or Madeira. If fresh thyme is unavailable, use half the amount of dried thyme.
•Perfect Texture: For the smoothest mousse, ensure the livers are slightly pink in the center before blending. Overcooked livers can result in a grainy texture. Passing the blended mixture through a fine-mesh sieve is also key for an extra silky finish.
•Fun Fact: The clarified butter topping isn't just for aesthetics; historically, it served as a protective seal to prevent oxidation and extend the shelf life of pâtés and mousses before modern refrigeration was common.
