Lemon Posset Recipe

4.5 from 120 reviews

Lemon Posset is a classic British dessert known for its creamy, silky texture and bright lemon flavor. Made with just three simple ingredients—cream, sugar, and lemon juice—this no-bake treat is easy to prepare and perfect for a refreshing, elegant dessert. The rich cream is boiled with sugar, then combined with tangy lemon juice and chilled until set, resulting in a luscious, velvety custard that melts in your mouth. Garnish with fresh lemon slices or berries for a beautiful presentation.

Ingredients

Scale

Posset Mixture

  • 2 cups heavy whipping cream
  • 2/3 cup granulated sugar
  • 5 Tbsp fresh lemon juice (about 3 lemons)

For Serving (Optional)

  • Lemon slices or fresh berries
  • Whipped cream (optional)

Instructions

  1. Boil: In a small saucepan, combine the heavy cream and granulated sugar. Stir continuously over medium heat to dissolve the sugar completely. Bring the mixture to a boil, then reduce the heat slightly to maintain a steady medium boil. Let it boil gently for 5 minutes, careful not to let it boil over.
  2. Add lemon: Remove the saucepan from heat and stir in the fresh lemon juice thoroughly. Set the mixture aside to cool for 15 minutes. Then strain it through a fine mesh sieve into a large measuring cup or bowl to catch any solids and ensure a smooth texture.
  3. Fill: Pour the strained lemon posset mixture evenly into 6 ramekins or into 10-12 hollowed-out lemon halves if you prefer an elegant presentation. Fill each container about three-quarters full to allow the posset to set properly.
  4. Refrigerate: Place the filled ramekins or lemon halves in the refrigerator. Chill for at least 2 hours, or until the posset is fully set and has a firm but creamy consistency.
  5. Serve: Just before serving, top each posset with a dollop of whipped cream if desired. Garnish with a lemon slice or fresh berries for a vibrant, attractive finish.

Notes

  • Use fresh lemon juice for the best flavor and to ensure the posset sets properly due to the acidity.
  • Heavy cream is essential for the creamy texture; do not substitute with lighter creams.
  • Straining the mixture removes any curdled bits and ensures a smooth, silky finish.
  • You can prepare the posset mixture a day ahead and refrigerate it for convenience.
  • Serve chilled for the best texture and taste.
