Duck Liver Mousse & Almond Financiers Recipe

Prepare and clean livers

Rinse the duck livers under cold water and pat dry with paper towels. Trim away any greenish bile, connective tissue and large blood vessels. Cut livers into roughly even pieces so they cook evenly.

Cook aromatics and deglaze

In a medium skillet over medium-low heat, melt 20 g of the unsalted butter. Add the chopped shallot and crushed garlic and sweat gently until soft and translucent, about 3–4 minutes—do not brown. Add the thyme and the duck livers and increase heat to medium. Sear the livers briefly, about 1–2 minutes per side, so the exterior is lightly colored but the interior stays tender.

Deglaze and simmer

Pour the white wine and brandy over the livers and use a wooden spoon to scrape any browned bits from the pan. Allow the alcohol to reduce for 1–2 minutes. Pour in the heavy cream, reduce heat to low and simmer very gently for 2–3 minutes to finish cooking the livers; they should be just cooked through and still tender inside. Turn off the heat and let cool slightly.

Optional: bloom gelatin

If using gelatin for a firmer set, sprinkle the gelatin over 15 ml cold water in a small bowl and let it bloom for 5 minutes. Warm gently (microwave 5–8 seconds or over a pan) until dissolved but not boiling, then stir into the warm cream-liver mixture.

Blend and pass

Transfer the cooked livers, aromatics, and pan juices to a food processor or blender. Add the remaining 40 g unsalted butter (cut into pieces), salt and pepper. Purée on high until very smooth, about 1–2 minutes. If desired for an ultra-silky texture, pass the purée through a fine-mesh sieve into a bowl using a spatula, pressing to remove any graininess.

Chill and set

Taste and adjust seasoning. Spoon the mousse into a serving ramekin or small terrine. Smooth the top and pour the melted butter over the surface to seal (this keeps the mousse fresh and adds flavor). Refrigerate for at least 3 hours, ideally overnight, until fully set.

Prepare dry ingredients

Preheat the oven to 200°C (390°F). In a bowl, whisk together the almond flour, all-purpose flour, and confectioners' sugar until evenly combined and lump-free. Add a pinch of fine sea salt and mix.

Beat egg whites

In a separate bowl, lightly whisk the egg whites just until foamy — you do not want stiff peaks, only slightly aerated whites. Fold the egg whites gently into the dry mixture until combined; a few streaks are fine.

Brown the butter

In a small saucepan over medium heat, melt the 100 g unsalted butter and continue cooking until it turns a deep golden brown with a nutty aroma (beurre noisette), about 4–6 minutes. Watch carefully to avoid burning. Remove from heat and let cool slightly for 2 minutes, then stir in the vanilla extract.

Combine batter

Slowly pour the warm browned butter into the almond-egg-white mixture while folding gently to create a smooth batter. The butter should be warm but not so hot that it cooks the egg whites. Let the batter rest at room temperature for 10–15 minutes — this helps relax the flour and improves texture.

Fill molds and bake

Butter and flour or spray a financier or small muffin pan. Spoon batter into the molds filling about 3/4 full. Sprinkle sliced almonds on top if using. Bake in the preheated oven for 10–14 minutes, until edges are golden and centers spring back lightly when touched. Rotate the pan halfway through baking for even color.

Cool

Remove financiers from oven and allow to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Financiers are best served slightly warm or at room temperature.

Portion: If you prepared the mousse in a larger terrine, scoop or slice 12 even portions. Arrange one portion of duck liver mousse on each plate or serve ramekins at the center.

Accompaniments: Place 1 financier alongside each mousse portion. Add 1 small cornichon or a piece of pickled shallot and a few crusty bread slices or crackers per serving. Garnish with microgreens or a small sprig of thyme/chives.

Serving temperature and storage: Serve mousse chilled with financiers at room temperature or slightly warm. Refrigerate any leftover mousse (sealed with melted butter or plastic wrap) for up to 3 days. Store financiers in an airtight container for 1–2 days.
