Directions

  1. Prepare the serving bowls

    Set six 5-ounce ramekins or shallow heat-safe bowls on a small tray that fits level in the refrigerator. Place a fine-mesh strainer over a heat-safe measuring jug or bowl with a pouring spout.

  2. Warm the lemon cream

    Combine the heavy cream, sugar, salt and lemon zest in a heavy 3-quart saucepan. Warm over medium heat, stirring until the sugar dissolves and the cream steams. Do not walk away; cream rises quickly once it boils.

  3. Boil for exactly 3 minutes

    When bubbles cover the surface, reduce the heat enough to maintain a controlled full boil. Boil for 3 minutes, stirring and scraping the bottom continuously with a heatproof spatula. The mixture should reduce slightly without scorching or boiling over.

  4. Add the lemon juice

    Remove the saucepan from the heat and wait 1 minute for the bubbling to subside. Whisk in the strained lemon juice gradually. The cream will remain pourable but should thicken enough to lightly coat the spatula.

  5. Rest and strain

    Let the lemon cream stand undisturbed for 8 minutes so the acid can begin thickening the dairy. Pour it through the prepared fine-mesh strainer, pressing only gently on the zest, for the exceptionally smooth texture shown in the photograph.

  6. Portion and chill

    Divide the mixture evenly among the six ramekins, about 1/2 cup each. Cool uncovered for 20 minutes, then cover without touching the surface and refrigerate for at least 4 hours, until softly set and no warmer than 40°F. Overnight chilling gives the cleanest texture.

  7. Toast the almonds

    Put the sliced almonds in a dry skillet over medium-low heat. Cook for 3 to 5 minutes, stirring constantly, until pale gold and fragrant. Move them to a cool plate immediately; they darken fast from residual heat.

  8. Finish like the photograph

    Just before serving, uncover the cold possets and scatter about 1 tablespoon toasted almonds across each pale-yellow surface. Serve in the ramekins so the delicate set remains intact.

Why this works

Why it worksBoiling dissolves the sugar, evaporates a controlled amount of water and concentrates the cream so it can form a spoonable set.
Why it worksLemon acid changes the structure of the cream's milk proteins; the measured ratio thickens reliably without eggs, starch or gelatin.
Why it worksStraining removes zest and any tiny cooked-milk particles, while adding almonds only at serving time preserves the contrast between silky cream and crisp garnish.

Swaps & notes

Easy swaps

  • For lime posset, replace the lemon zest and juice with equal measured amounts of fresh lime zest and strained lime juice; the flavor will be sharper and more floral.
  • For a nut-free finish, omit the almonds and top each chilled posset with 2 tablespoons of sliced strawberries or raspberries immediately before serving.
  • Caster sugar can replace granulated sugar gram for gram. Do not reduce the sugar below 120 grams, because sugar affects both the flavor balance and the finished texture.

Cook notes

  • Use true heavy cream with at least 36% milk fat. Half-and-half, light cream and most plant milks do not contain enough dairy fat and protein to set by this method.
  • Fresh strained lemon juice provides predictable acidity and clean flavor. Bottled juice can taste harsh and its acidity varies by product.
  • The posset should tremble slightly and yield easily to a spoon. A rubbery or sliceable set usually means the cream boiled too long or too much juice was added.

Storage

Keep possets covered and refrigerated at 40°F or colder for up to 3 days. Store toasted almonds separately at room temperature in an airtight container and add them only before serving. Do not freeze the possets; thawing can make the cream grainy and cause liquid to separate.

Questions

Why did my lemon posset not set?

The usual causes are low-fat cream, too little acid or an abbreviated boil. Use 36% heavy cream, measure 90 milliliters strained juice and maintain a controlled boil for the full 3 minutes before chilling at least 4 hours.

Why does my posset taste grainy?

The cream may have scorched or the juice may have been whisked in while the boil was still violent. Use a heavy pan, stir continuously, wait 1 minute off heat before adding juice and strain before portioning.

Can lemon posset be made for a dinner party?

Yes. Make and chill it 1 to 2 days ahead, keeping each ramekin covered after cooling. Toast the almonds separately and scatter them on only when serving so they stay crisp.
