Ingredients You’ll Need
One of the best things about this Lemon Posset Recipe is how few ingredients it requires. Each element plays a crucial role, contributing to the silky texture, sweetness, and that signature burst of lemon zing.
- Heavy whipping cream: The star of the dessert, providing the luscious, smooth base that transforms into a creamy pudding.
- Granulated sugar: Just enough sweetness to balance the tartness without overpowering the lemon.
- Lemon juice: Freshly squeezed is best to deliver bright, natural acidity and depth of flavor.
- Lemon slice or berries: Optional, but perfect for adding a pop of color and extra freshness when serving.
How to Make Lemon Posset Recipe
Step 1: Boil the Cream and Sugar
Begin by combining the heavy whipping cream and sugar in a small saucepan. Stir continuously as you bring the mixture to a boil. It’s important to keep an eye on the heat to prevent the cream from boiling over, but maintaining a steady medium boil for five minutes is key — this step thickens the cream perfectly to give your posset its signature rich texture.
Step 2: Add the Lemon Juice
Once your cream and sugar have boiled adequately, remove the saucepan from the heat and stir in the lemon juice. This is where the magic happens — the acid in the lemon curdles the cream just enough, creating a silky, slightly set mix. Let it cool for about 15 minutes before straining it through a fine mesh sieve. This removes any lumps and creates that perfectly smooth consistency.
Step 3: Fill Your Serving Containers
Whether you choose charming ramekins or even hollowed-out lemon halves for a whimsical touch, pour the strained mixture until it is about three-quarters full. This allows the posset room to set properly for that delightful, jiggly firmness.
Step 4: Refrigerate and Set
Pop your possets into the refrigerator and let them chill for at least two hours. During this time, they’ll firm up into the velvety texture that makes this dessert stand out. Once set, they’re ready for the finishing touches and serving.
How to Serve Lemon Posset Recipe

Garnishes
Simple garnishes like a dollop of freshly whipped cream or a thin lemon slice elevate the posset’s visual appeal and add delightful contrast. Bright berries, such as raspberries or blueberries, introduce a juicy tang and vibrant color that pairs beautifully with the creamy base.
Side Dishes
Because Lemon Posset is light and refreshing, it pairs wonderfully with crisp, buttery cookies like shortbread or delicate meringues. You could even serve it alongside a subtly sweet almond cake to round out a more substantial dessert course without overwhelming the palate.
Creative Ways to Present
For a charming twist, try serving your posset in hollowed lemon halves or clear shot glasses layered with crushed biscotti or cookie crumbs. These presentations add texture and make your Lemon Posset Recipe feel even more special when entertaining guests.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers, Lemon Posset keeps beautifully covered in the refrigerator for up to three days. Just be sure to use airtight containers to protect the delicate flavors and creamy texture.
Freezing
Freezing posset isn’t usually recommended as the texture can suffer, becoming grainy or separated upon thawing. This dessert shines best when enjoyed fresh and chilled.
Reheating
Since posset is a cold-set dessert, reheating isn’t necessary or advisable. Instead, allow refrigerated portions to come to a gentle room temperature if you prefer it slightly less chilled before serving.
FAQs
Can I use lemon juice from a bottle for this Lemon Posset Recipe?
While fresh lemon juice provides the brightest and most natural flavor, bottled lemon juice can be used in a pinch. Just make sure it’s pure lemon juice without additives to maintain the dessert’s authentic taste.
Can I substitute the heavy cream with something lighter?
This recipe relies on the richness of heavy cream for its creamy texture, so using alternatives like half-and-half or milk will affect the final consistency and flavor. For best results, stick to heavy whipping cream.
How long does the Lemon Posset need to chill?
At minimum, allow at least two hours for chilling in the refrigerator. This gives the posset enough time to fully set into its characteristic silky firmness.
Is this recipe suitable for making in advance for parties?
Absolutely! Lemon Posset is a great make-ahead dessert because it stores well in the refrigerator and can be prepared a day or two before your event.
Can I add other flavors to the Lemon Posset?
Yes, you can experiment by adding a splash of vanilla extract or infusing the cream with herbs like lavender for a unique twist. However, the classic lemon flavor is delightfully bright and satisfying on its own.
