Lemon Posset is a classic British dessert featuring a rich, creamy texture made from gently simmered heavy cream, sugar, and fresh lemon juice.

Ingredients

Main Ingredients

  • 1 pint (2 cups) heavy cream
  • ½ cup sugar
  • 1 ½ teaspoons grated lemon zest
  • ⅓ cup lemon juice
  • ¼ teaspoon vanilla extract

Optional Garnishes

  • Fresh berries (blackberries, raspberries, or blueberries)
  • Mint leaves
  • Crushed graham crackers or pistachios

Instructions

  1. Combine and Heat Cream, Sugar, and Zest: In a medium saucepan over medium heat, combine the heavy cream, sugar, and grated lemon zest. Stir frequently to dissolve the sugar and prevent sticking. Keep a 2-cup measuring cup nearby to monitor the volume as the cream reduces.
  2. Simmer Until Reduced: Bring the mixture to a gentle simmer, adjusting heat to maintain a gentle simmer and avoid boiling over. Continue cooking and stirring occasionally until the cream has reduced to 2 cups, which takes approximately 15 to 20 minutes.
  3. Remove From Heat and Add Flavorings: Take the saucepan off the heat, then stir in the fresh lemon juice and vanilla extract. Allow the mixture to rest for 20 minutes to meld the flavors and slightly thicken.
  4. Strain the Mixture: Pour the mixture through a fine-mesh strainer into a bowl to remove the lemon zest, discarding the zest afterward.
  5. Divide Into Serving Dishes: Evenly divide the strained mixture among 8 ramekins or serving glasses.
  6. Chill Until Set: Refrigerate the possets uncovered for at least 3 hours or until fully set. Once chilled, cover with plastic wrap or lids for storage. They keep in the refrigerator for up to 1 week or can be frozen for up to 3 months.
  7. Serve with Garnishes: Before serving, if frozen, defrost in the refrigerator for at least 30 minutes and then rest at room temperature for 10 minutes. Garnish with fresh berries, mint leaves, or crushed nuts as desired for a decorative and flavorful finish.

Notes

  • Use a gentle simmer to prevent the cream mixture from boiling over or scorching.
  • Grated lemon zest must be finely prepared to infuse flavor effectively without unwanted texture.
  • Straining the mixture ensures a smooth, velvety posset without zest bits.
  • Possets can be made ahead and stored refrigerated for convenience.
  • Allowing possets to rest at room temperature before serving enhances their creamy texture.
  • Freezing is optional but extend shelf life; thaw properly before serving to maintain texture.
