Classic English Lemon Posset

Lemon Posset is an easy-to-make classic English dessert dating back to the Middle Ages. The modern version is chilled, with a velvety smooth texture that magically congeals with only three ingredients – cream, sugar, and lemon. Unlike Lady Macbeth, who drugged King Duncan’s guards with poisoned posset, you can WOW your guests.

  • 2 cups (16 ounces, 473 ml) heavy cream (See Tip 1)
  • cup (4.67 ounces, 132 grams) granulated sugar
  • 1 Tablespoon lemon zest
  • 6 Tablespoons (3 ounces, 89 ml) fresh lemon juice (2 to 3 lemons)


  • Combine cream, sugar, and lemon zest in a medium saucepan. Bring to a boil over medium heat. Continue to boil, stirring frequently to dissolve sugar. Cook until mixture is reduced to 2 cups, 8 to 10 minutes.
  • Remove the saucepan from heat; stir in lemon juice. Let sit undisturbed until the mixture is cooled slightly and skin forms on top for about 20 minutes. Strain through a fine-mesh strainer into a bowl; discard the zest. Divide the mixture evenly among 4 individual serving glasses or 6 individual ramekins. (See Tip 2)
  • Refrigerate, uncovered, until set, at least 3 hours. Once chilled, possets can be wrapped in plastic wrap and refrigerated for up to 2 days. Unwrap and let sit at room temperature for 10 minutes before serving. If desired, garnish with whipped cream and raspberries.
  • Yield: 4 to 6 servings.


  1. It's important to use high-quality heavy cream in this recipe. The reason is that the fats in the cream combine with the acid in the lemon juice to produce a thick, velvety texture. Do not try substituting half and half or whole milk.
  2. I like to strain the Lemon Posset into a measuring cut to make it easier to transfer to individual serving dishes.
