I published this recipe for Lemon Posset with Raspberries a few years ago after a complete kitchen disaster. I was trying to make a fancy layered dessert for a dinner party, and everything went wrong.
My meringue wept. My custard split. I was nearly in tears with only an hour before guests arrived. Then I remembered this magical, three-ingredient dessert. It saved the night and became my go-to for every “I need something impressive, fast” moment since.
My secret for this recipe is patience, not complexity. You just simmer, stir, and let time work its magic in the fridge. The transformation from a thin, sweet liquid into the most luxuriously creamy, tangy dessert feels like pure kitchen alchemy. It’s the ultimate proof that simple is often spectacular.

Notes
Enjoy your homemade Lemon Posset with Raspberries Recipe!
The magic happens when lemon juice meets hot, sweet cream. The acid thickens the cream without any eggs, gelatin, or cornstarch. It’s a pure, clean set that results in a texture somewhere between a pudding and a panna cotta.
It’s intensely lemony, not overly sweet, and the fresh raspberries on top add a beautiful pop of color and a tart contrast. This is a dessert that truly speaks for itself.
The Full Ingredient List
Gathering your ingredients is the first step to this easy treat. You’ll be amazed at how such a short list creates such a big flavor.
- 2 cups (480ml) heavy whipping cream
- 2/3 cup (135g) granulated sugar
- 1/3 cup (80ml) fresh lemon juice (from about 2-3 large lemons)
- Zest of 1 large lemon
- 1 teaspoon pure vanilla extract
- Pinch of fine sea salt
- 6 ounces (about 1 1/2 cups) fresh raspberries, for serving
My Step-by-Step Method
Follow these steps closely, and you really can’t go wrong. I’ve made this dozens of times, and this method is foolproof.
- Get your serving glasses ready. Place 4-6 small glasses or ramekins on a tray. This makes pouring easier later.
- Zest and juice your lemons. Do this first! Zest one lemon finely, then juice all your lemons until you have 1/3 cup. Strain the juice to remove any seeds or pulp. Fresh lemon juice is non-negotiable for the best flavor and proper set.
- Simmer the cream and sugar. In a medium saucepan, combine the heavy cream, sugar, lemon zest, and that pinch of salt. Warm it over medium heat, stirring frequently, until the sugar is fully dissolved and the mixture just comes to a simmer. You’ll see small bubbles around the edges. Let it bubble gently for exactly 3 minutes, stirring often. This step is crucial for the right texture.
- Cool slightly, then add lemon juice. Take the pan off the heat and let it sit for 2-3 minutes. Then, stir in the vanilla extract and the fresh lemon juice. You’ll see it thicken slightly almost immediately.
- Strain and pour. Pour the mixture through a fine-mesh sieve into a large jug or bowl with a spout. This catches the zest and any potential little bits. Carefully divide the posset mixture among your prepared glasses.
- Chill until set. Let the glasses cool to room temperature, then cover them loosely with plastic wrap. Refrigerate for at least 4 hours, but overnight is ideal. The possets will firm up beautifully.
- Serve. Just before serving, top each posset with a handful of fresh raspberries. That’s it!
My Top Tips for Success
- Use full-fat heavy cream. Lower-fat alternatives will not set properly. You need that rich fat content for the magic to happen.
- Don’t skip the simmering time. Those 3 minutes of gentle bubbling are what concentrate the cream and sugar, giving the final dessert its perfect, sliceable consistency.
- Let the cream mixture cool for a few minutes before adding the lemon juice. If the cream is boiling hot, the acid can sometimes cause it to separate. A brief cool-down prevents this.
- For the prettiest presentation, wait to add the raspberries until right before you serve. This keeps them fresh and prevents them from bleeding juice into the creamy posset.
Common Mistakes to Avoid
I’ve learned from my own errors so you don’t have to. Here are the main pitfalls.
Adding lemon juice to boiling cream. This is the biggest one. If the cream is too hot, the acid can cause it to curdle or separate. Always let it cool off the heat for 2-3 minutes first.
Not simmering long enough. If you don’t simmer the full 3 minutes, the posset may not set firmly. It might still taste good, but it will be more soupy than spoonable. Trust the timer!
Using bottled lemon juice. The flavor is flat and often contains preservatives that can interfere with the setting process. Fresh lemons are the heart of this dessert.

FREQUENTLY ASKED QUESTIONS
Can I make lemon posset ahead of time?
Absolutely! In fact, I highly recommend it. These need at least 4 hours to set, but making them a full day ahead is perfect. Just keep them covered in the fridge until you’re ready to serve.
My posset didn’t set. What went wrong?
The most common reasons are not simmering the cream mixture for the full 3 minutes, or using a cream with lower fat content. Make sure you use heavy whipping cream and watch the clock during the simmering step.
Can I use a different fruit?
Yes! While raspberries are my favorite, this posset pairs wonderfully with many berries. Try blueberries, blackberries, or a mix. A few shortbread cookies on the side are also a delicious addition.
