Course Dessert
Cook Time 15 minutes
Chill 4 hours
Servings 6 half cup servings


  • 2 ¼ cups heavy cream
  • ¾ cups sugar
  • 5 tablespoons fresh lemon juice
  • 4 tablespoons fresh lime juice


  • 1 teaspoon lemon zest
  • 1 teaspoon lime zest
  • 1 teaspoon sugar
  • cool whip or homemade whipped cream, optional


  • Using a small saucepan, heat the heavy cream and sugar over medium-high heat. Bring to a boil, and boil for 3 minutes, stirring constantly. If the boiling cream is bubbling too much, turn the heat down to medium, but maintain a boil. To prevent it from boiling over, lift the saucepan off the burner for a few seconds, return it to the burner and continue stirring.
  • Remove from heat and whisk in the lemon and lime juice. Pour the mixture into the serving dishes. Cover and chill in the refrigerator for at least 4 hours or until set.


  • When ready to serve, zest one lemon and one lime (1 teaspoon of each). Mix with the sugar. Sprinkle over the posset and garnish with whipped cream (optional).


The serving size for this dessert is just 1/2 cup. It is a rich dessert yet delicate. You certainly could make the serving sizes bigger, but you would get fewer servings.
For 1/2 cup servings, ramekins or custard cups work perfectly for this recipe.
