The first time I tried a lemon posset, I was completely floored. A dessert this silky, this decadent, and this bursting with bright, zesty flavor couldn’t possibly be easy to make, right?

The acid from the lemon juice reacts with the heated heavy cream, causing it to thicken into a luxuriously smooth and creamy pudding as it chills.
The lemon posset recipe is the ultimate elegant, make-ahead dessert. It feels fancy enough for a special occasion or dinner party, but is so simple you can whip it up for a weeknight treat. If you’re looking for a recipe that delivers maximum “wow” factor with minimal effort, you’ve found it.

Ingredients
- 2 cups heavy cream
- 2/3 cup granulated sugar
- 1 1/2 tablespoons lemon zest, (about the zest of 2 large lemons)
- 6 tablespoons freshly squeezed lemon juice
- 1 cup raspberries or blueberries for serving
How to make Lemon Posset Recipe
Step 1: Before you begin, get your equipment ready. Set out six small ramekins or dessert cups. Have a 2-cup glass measuring cup nearby to check your progress.
Step 2: In a medium saucepan, combine the heavy cream, granulated sugar, and lemon zest. Place the pan over medium heat and bring the mixture to a simmer. Let it simmer for 8-12 minutes, stirring often to make sure the sugar dissolves and the cream doesn’t burn on the bottom. The goal is to reduce the mixture to exactly 2 cups. Start checking the volume around the 8-minute mark by carefully pouring it into your glass measuring cup. It’s crucial to stay by the stove, as cream can boil over in an instant.
Step 3: Once the mixture has reduced to 2 cups, pour it into the glass measuring cup and let it cool for about 20 minutes. This slight cooling prevents the mixture from curdling when you add the lemon juice. After cooling, stir in the 6 tablespoons of fresh lemon juice.
Step 4: Place a fine-mesh strainer over a separate bowl and pour the cream mixture through it. This step is essential for catching the lemon zest and any cooked bits, ensuring your final posset is perfectly smooth. Discard the contents of the strainer.
Step 5: Carefully divide the strained liquid evenly among your six prepared ramekins. Place them in the refrigerator, uncovered, and let them chill for at least 3 hours, or until fully set. Once set, you can cover them with plastic wrap.
How to serve the Lemon Posset Recipe
These lemon possets are stunning on their own, but a simple garnish takes them to the next level. The bright, tangy creaminess pairs wonderfully with the sweetness of fresh fruit. Serve the chilled possets straight from the fridge, topped with a generous handful of fresh raspberries or blueberries. For an extra touch of elegance, add a small mint sprig or a delicate, buttery shortbread cookie on the side for dipping.
How to store Lemon Posset Recipe
One of the best things about this dessert is that it can be made in advance. After the initial 3-hour chilling period (uncovered), you can cover each ramekin tightly with plastic wrap. The possets will keep beautifully in the refrigerator for up to 2 days. The flavor may even deepen slightly overnight. Keep them chilled right up until you are ready to serve.
Tips to make
Use Fresh Lemons: For the best, brightest flavor, always use freshly squeezed lemon juice and fresh zest. Bottled lemon juice doesn’t have the same vibrant taste and can affect the final texture.
Don’t Skip the Straining: This step is the secret to a professional, silky-smooth texture. Straining removes the zest and any tiny bits of cooked cream, which makes a huge difference in the final product.
Watch the Pot: We can’t say it enough! A simmering pot of cream can go from a gentle bubble to a full-on boil-over in a matter of seconds. Stay close and stir frequently.
Measure the Reduction: Reducing the cream to exactly 2 cups is key. This concentrates the milk fats, which is what helps the posset set properly when it reacts with the lemon’s acid. Not reducing it enough can lead to a runny dessert.
FAQs About Lemon Posset Recipe
Why didn’t my posset set?
The most common reason for a runny posset is that the cream mixture wasn’t simmered long enough. It’s crucial to reduce the liquid to exactly 2 cups. This concentrates the fat and proteins in the cream, which are needed to react with the lemon’s acid to create the set. Make sure you are boiling it for at least 8 minutes and measuring the volume.
Can I use a different kind of citrus?
Yes, you can experiment with other citrus fruits like limes or Meyer lemons for a different flavor profile. Limes work as a nearly one-to-one substitute. If using a less acidic fruit like oranges, you may need a little more juice, and the set might be slightly softer. The classic lemon version is popular for its perfect balance of tang and a reliable set.
Can I use milk or half-and-half instead of heavy cream?
Unfortunately, no. This recipe relies entirely on the high fat content of heavy cream (typically 36% or more) to set properly. Milk or half-and-half do not have enough fat and will not thicken when combined with the lemon juice, resulting in a thin, soupy mixture.
