What Are Sweet and Tangy Lemon Posset?
Sweet and Tangy Lemon Posset is a classic British style citrus dessert made by gently heating heavy cream with sugar and fresh lemon juice until it thickens naturally. The acid from the lemons reacts with the cream, creating a silky custard like texture without eggs, gelatin, or cornstarch. The result is luxuriously smooth, rich yet refreshing, and perfectly balanced between creamy and bright. Served in hollowed lemon shells or elegant glasses, this simple dessert feels sophisticated but is secretly one of the easiest things you will ever make.
Ingredients You Will Need
Heavy whipping cream
Granulated sugar
Fresh lemons
Fresh lemon juice and zest
Our Tips for Sweet and Tangy Lemon Posset
Do not reduce the cream fat content. The recipe relies on heavy cream with at least 33 percent fat to properly set. Lower fat cream will not thicken correctly.
Let the cream mixture gently bubble for about 3 minutes after it begins to simmer. This ensures the sugar fully dissolves and the posset sets firmly once chilled.
Strain before pouring. Even if you think it looks smooth, straining removes zest bits and any tiny curdled pieces for a perfectly silky finish.
Chill longer than you think. While it may feel set after one hour, two to three hours gives the best texture and flavor.
How to Store Sweet and Tangy Lemon Posset
Refrigerator: Cover each lemon shell tightly with plastic wrap or transfer to airtight containers. Store in the refrigerator for up to 3 days. Keep chilled until ready to serve for the best texture.
Freezer: For longer storage, place the posset in freezer safe airtight containers without the lemon shells. Freeze for up to 1 month. Thaw overnight in the refrigerator. Note that freezing may slightly alter the silky texture but the flavor will remain bright and delicious.

Ingredients
- 2 ½ cups heavy whipping cream, at least 33 percent fat
- 1 cup granulated sugar
- 6 large lemons
- ⅓ cup fresh lemon juice
- 2 tablespoons lemon zest
Instructions
- Prepare the Lemon Shells: Slice the lemons in half lengthwise and carefully scoop out the pulp, keeping the shells intact. Strain the pulp to extract fresh juice and measure the required amount. Set shells aside on a tray so they sit level.
- Heat the Cream: In a medium saucepan over medium heat, combine heavy cream and sugar. Stir until the sugar dissolves completely. Once the mixture begins to gently bubble, allow it to simmer for 3 minutes, stirring occasionally.
- Add Lemon: Remove the saucepan from heat. Stir in the fresh lemon juice and lemon zest until fully combined.
- Strain and Pour: Let the mixture cool for 10 minutes, then strain through a fine mesh sieve into a measuring cup. Carefully pour into the prepared lemon shells or serving glasses.
- Chill Until Set: Allow to cool at room temperature for about 20 minutes. Cover loosely with plastic wrap and refrigerate for at least 2 to 3 hours until fully set.
Notes
- Cream Quality Is Everything: Use heavy cream made from real milk with at least 33 percent fat. Ultra light or whipping toppings will not set properly.
- Simmering Activates the Set: Allowing the cream to gently simmer for a few minutes ensures the proteins and sugar properly interact with the acid from the lemons, creating that naturally thick texture.
- Fresh Juice Matters: Bottled lemon juice lacks the brightness and acidity balance needed for the perfect set and flavor. Always use freshly squeezed lemons.
