Classic English Lemon Posset

Lemon Posset is a 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 with this simple to make and elegant dessert from Cooks Illustrated.

  • 2 cups (16 ounces, 454 ml) heavy cream
  • cup (4.67 ounces, 132 grams) granulated sugar
  • 1 Tablespoon lemon zest
  • 6 Tablespoons (3 ounces, 85 ml) fresh lemon juice (2 lemons)


  • Combine cream, sugar, and lemon zest in 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 saucepan from heat; stir in lemon juice. Let sit until mixture is cooled slightly and skin forms on top, about 20 minutes. Strain through fine-mesh strainer into bowl; discard zest. Divide mixture evenly among 4 individual serving glasses or 6 individual ramekins.
  • 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.
