Instructions
- 1
In a clean glass container, combine 500g heavy cream (36-40% fat) and 150g roasted walnuts. Cover and refrigerate for 12 to 24 hours. The cold dairy pulls out lipid-soluble walnut aromatics while leaving astringent skin tannins behind.
5 min
Tip: Do not rush with heat. Cold infusion delivers a clean, rounded nut profile without bitterness.
- 2
Set a fine-mesh sieve over a medium saucepan. Pour the cold-infused mixture through, pressing gently on the solids with a silicone spatula to extract the flavored cream without crushing nut paste into the liquid. You should yield roughly 420g of infused cream.
5 min
Tip: Wipe your counter down before moving to the stove. Precision starts with an uncluttered station.
- 3
Add 100g granulated sugar to the strained walnut cream in the saucepan. Set over medium heat and bring to a rolling boil, stirring occasionally. Once boiling, set a timer for 3 minutes and let it boil steadily, stirring gently to prevent boiling over.
6 min
Tip: Do not skip the 3-minute boil. The rolling boil concentrates milk proteins and destabilizes casein micelles so the acid can set them later.
- 4
Pull the saucepan completely off the heat. Immediately whisk in 45g fresh lemon juice. The mixture will thicken slightly within seconds. Pour evenly into four small glasses or ramekins (about 110g per serving). Let stand at room temperature for 20 minutes, then transfer to the refrigerator to chill for at least 3 hours until firmly set.
4 min
Tip: Let it cool. Future you deserves clean sets. Sticking warm glasses straight into an airtight box can trap condensation.
- 5
While the possets chill, make the tart reduction. In a small saucepan, combine 120g tart 100% pomegranate juice, 15g granulated sugar, and 5g fresh lemon juice. Simmer over medium-low heat for 6 to 8 minutes until reduced by half to a loose syrup (about 60g total). Let it cool completely to room temperature.
8 min
Tip: The reduction thickens as it cools. Pull it when it coats the back of a spoon lightly.
- 6
In a small dry bowl, toss together 40g roasted walnuts, 15g roasted cocoa nibs, and 2g flaky sea salt.
3 min
Tip: Keep this dry crunch mixture stored at room temperature until the exact moment of plating.
- 7
To serve, spoon 1 tablespoon of the cooled pomegranate reduction over the surface of each chilled walnut posset. Scatter the salted walnut-cocoa nib crunch right over the center.
3 min
Tip: Serve straight from the fridge. The contrast of ice-cold silken cream against room-temperature crunch is the whole game.
Chef's Notes
Why this works: Posset is the purest demonstration of minimalist pastry. No gelatin, no egg yolks, no cornstarch. Boiling heavy cream with sugar destabilizes the casein micelles; adding fresh lemon juice drops the pH to roughly 4.5, forcing those proteins to knit into a delicate, ultra-creamy gel as it cools. Walnuts contain intense tannins in their skins that can ruin a cooked custard with bitter astringency. Cold-infusing them into cold heavy cream overnight pulls purely the toasted, buttery walnut oils into the dairy fat while leaving harsh water-soluble tannins untouched. Contrast is the secret ingredient: rich walnut cream meets high-wire pomegranate acid and bittersweet crunch. Fix it fast: If your posset feels too loose after 3 hours, your cream likely didn't boil long enough to concentrate the proteins, or your lemon juice lacked acidity. Return the mixture to a saucepan, add 1 extra teaspoon of lemon juice, boil for 1 minute, and rechill. Precision is freedom: always weigh your lemon juice.
