If you are looking for a smooth, creamy, and decadent dessert, then look no further. Not to mention it’s effortless to put together with just 4 ingredients!

This is one of those desserts that will wow your friends and family with just one bite. The texture of this dessert is so incredibly smooth, creamy, and decadent that everyone will assume you spent all afternoon creating this bit of perfection. But it will be our secret that it took maybe 15 minutes and 4 simple ingredients to make.

What is a posset? It’s a dessert that originated in England as a creamy beverage curdled with wine, ale, or liquor and flavored with spices. But today’s posset, which has been taken up by English celebrity chefs and cookbook writers and is starting to appear on American restaurant menus, is something altogether different: a chilled dessert with a luxurious texture that comes together almost by magic from nothing more than sugar, cream, and citrus juice. The three ingredients work perfectly together to get that silky, smooth texture. The citrus reacts with the cream (there is a whole chemical reaction that you can read about here) and causes the cream to thicken and while the sugar gives a silkiness to the texture.

This is one of those recipes where you can not make substitutions, except for changing the citrus. You must have the fat from the heavy cream to react with the acid in the citrus. So you can not use milk or lower-fat cream; it must be heavy cream; otherwise, you’ll be drinking your posset. The portions are meant to be small, usually just half a cup, so you don’t need to worry too much about the calories. Just dive right into the silky decadence and enjoy!

I will be experimenting with other citrus flavors, so stay tuned for more posset recipes!

This dessert pairs well with a garnish of berries; blueberries, raspberries, blackberries or even sliced strawberries.

To add another layer of elegance to the dessert, I like to combine a teaspoon of lime zest, a teaspoon of lemon zest, and a teaspoon of granulated sugar. Stir to combine, then sprinkle on top of the dessert. Trust me; you won’t regret this part one bit!

A dollop of cool whip or homemade whip cream and you’re set to go!

Cook Time 15 mins
Chill 4 hrs
Course Dessert
Servings 6 half cup servings


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


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


  • Using a small saucepan, put 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 burn for a few minutes, then return to the burner and continue stirring.
  • Remove from heat and whisk in the lemon and lime juice. Pour the mixture into 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 obviously would get fewer servings.
For 1/2 cup servings, ramekins or custard cups work perfectly for this recipe.
