Ingredients
To make the perfect lemon posset, you’ll need only a few basic ingredients:
- Heavy Cream: The base of this dessert, creating a rich and smooth texture.
- Sugar: Adds sweetness, balancing the tartness of the lemon.
- Lemons: Fresh lemons are essential for their zest and juice, which give the posset its refreshing citrus flavor.
Alternative Ingredient Suggestions
- Erythritol: For those following a keto or sugar-free diet, erythritol can replace sugar without altering the texture too much.
- Meyer Lemons: These are a sweeter variety of lemon that can provide a milder citrus flavor, perfect for those who prefer less tanginess.
Step-by-Step Instructions
Making lemon posset is easy! Just follow these simple steps:
- Heat the Cream: In a saucepan, combine the heavy cream and sugar. Heat it over medium heat, stirring occasionally until the sugar has dissolved and fine bubbles appear on the surface.
- Add Lemon Zest and Juice: Remove the saucepan from the heat. Stir in the lemon zest and fresh lemon juice.
- Cool the Mixture: Let the mixture cool for about 10 minutes. During this time, the cream will begin to thicken due to the reaction between the lemon juice and cream.
- Strain and Serve: Strain the mixture into your serving cups (or lemon shells if you’re feeling creative). Refrigerate for at least an hour to allow it to set properly.
- Serve and Enjoy: Once the posset has chilled and set, it’s ready to serve. You can garnish it with extra zest, berries, or mint for added flair.

Tips & Tricks
- Don’t Overheat the Cream: Ensure that you don’t let the cream boil. Heating it just until fine bubbles form is enough.
- Strain for Smoothness: Always strain the mixture to eliminate any lumps or curdled cream, ensuring a silky texture.
- Lemon Shells: If you’re using lemon shells for serving, be sure to wash the lemons thoroughly to remove any waxy coating.
Pairing Ideas and Variations
Lemon posset pairs wonderfully with fresh berries or a drizzle of honey. If you’re looking to add more texture, consider topping it with crumbled shortbread cookies or a few slivers of toasted almonds. For a different twist, try substituting the lemon juice with orange or tangerine juice for a unique citrus spin.
If you’re preparing this dessert for a dinner party, it can be made up to three days in advance, making it a great make-ahead option. Just keep it covered in the fridge and serve when ready.
Storing Lemon Posset
If you’ve made your lemon posset in individual cups, store them covered in the fridge for up to five days. If using lemon shells, consume the dessert within two days, as the shells may absorb too much moisture and lose their integrity.
Lemon posset is a versatile and delightful dessert that’s perfect for any occasion. Whether you serve it in lemon cups or elegant glass ramekins, it’s sure to impress your guests with its delicate, creamy texture and zesty flavor.

Frequently Asked Questions
1. Why is my lemon posset not setting properly?
There are several reasons why your lemon posset might not set properly. One common cause is using a heavy cream with low fat content, which is crucial for the posset to thicken. Ensure you’re using cream with at least 33% fat. Also, be sure not to overheat the cream or add too much lemon juice, as both can affect the setting process.
2. Can I use a different citrus fruit instead of lemon?
Yes! While lemon is the traditional fruit for posset, you can easily substitute other citrus fruits such as oranges, grapefruits, or tangerines. Each will provide a unique twist on the flavor, making it a fun way to experiment with this classic dessert.
3. How long does lemon posset last in the fridge?
Lemon posset can be stored in the fridge for up to five days if made in cups or small bowls. However, if you’re using lemon shells, it’s best to consume the posset within two days as the lemon peels may start to deteriorate and absorb too much moisture.
