How to Make Lemon Posset
Preparation
Have a 2-cup glass measuring cup ready as you prepare this simple dessert. You want to reduce the cream/lemon mixture to exactly 2 cups for the best consistency. The best way to do this is pour the mixture into the measuring cup once or twice during boiling to monitor the amount. Then, set out 6 small ramekins or dessert cups to pour the custard into.
Make the Posset
- Combine the heavy cream, sugar, and lemon zest in a medium or small saucepan and bring to boil over medium heat.
- Simmer the mixture over medium-high heat, stirring frequently to dissolve the sugar for 8-12 minutes. Do not leave the mixture unattended as it can boil over! Simmer until the mixture is reduced to 2 cups (start checking the amount around 8 minutes of simmering.)
- Pour the mixture into the 2-cup glass measuring cup and stir in the lemon juice. Let the mixture cool for about 20 minutes to room temperature.
- Strain the cream through a fine-mesh strainer into a bowl. Divide the cream evenly among the 6 individual ramekins or dessert cups.
- Refrigerate the custards (uncovered) for at least 3 hours. Then wrap in plastic wrap and refrigerate for up to 2 days.
- Serve topped with fresh berries. Enjoy!
Storage/Make Ahead Instructions
- Lemon posset can be covered in plastic wrap and stored in the fridge for up to two days.
- You can easily make the possets a day ahead, and then store them in the fridge overnight.
FAQs
Lemon posset is a very simple British dessert made of heavy whipping cream, lemon juice, lemon zest, and white sugar. If desired, you can top your lemon posset with fresh berries.
Posset is not baked and relies on citrus acid to set up the dessert, while panna cotta is uses gelatin to thicken the cream.

Expert Tips and Tricks

Would the posset still set if I use more lemon juice (like 3 lemons instead of 2)?
I love extra lemony desserts.
I would add some lemon extract rather than more lemon juice if you want extra lemon flavor. I hope this helps!
I need to make this sugar-free. If I use Splenda, will it thicken up enough, or would I need to add gelatin? Thanks.
I haven’t tried making this with Splenda so I’m not sure how it would turn out. My guess would be you’ll need to add 1 teaspoon of gelatin to the mixture while it’s heating to ensure the posset sets up. I hope this helps!
I’m confused. If your starting with 2 cups cream, how are you reducing it to 2 cups?
You’re also adding sugar and lemon juice – so the mixture starts off as more than 2 cups. I hope that makes sense!
Are you adding lemon juice while boiling or just zest. Or is it 2 cups of cream, sugar, and zest, reduce to two cups. I understood it as the juice went in only after the heating process.
Mine is chilling at the moment but the spatula was delightful!
You add just the lemon zest when it’s boiling and strain it out. This just adds a little more lemon flavor! I hope you enjoyed it 🙂
I was a little nervous to try this recipe because the boiling down part seemed fancier than what I am used to. It ended up being really easy and the result was delicious! Fiancé asked if we can add this one to our list to make again.
So simple and so delicious. I have a ton of lemons and this a great and tasty way to go thru a couple.
I’m so glad you enjoyed the recipe! It’s one of my favorite ways to use up lemons too 🙂
Do you have a dairy free option for this?
Do you think coconut cream would give a similar result? I love all things lemon especially with any berry.
I would need to test this with coconut cream! I’m not sure how it would turn out – my guess is it wouldn’t have the same texture!
I am with you, Rhonda. I am Paleo and dairy free. Was wondering if canned coconut cream would you substitute for heavy whipping cream. I will try it.
