Ingredients You’ll Need For Lemon Peach Posset:

The beauty of lemon posset lies in how a few simple ingredients come together to create something truly special. Since there are only four main ingredients, it’s worth using the best quality you can find.

Heavy cream forms the base of the dessert and gives the posset its signature rich, velvety texture. Make sure to use full-fat cream, as lower-fat alternatives won’t set properly.
Caster sugar sweetens the cream while balancing the sharp, citrusy notes of the lemon. Its fine texture also helps it dissolve quickly into the warm cream.
Fresh lemon juice is the star of the show. Not only does it add bright, tangy flavour, but it also reacts with the cream to naturally thicken and set the dessert. Freshly squeezed lemon juice will always give you the best flavour.
Peaches are not a classic addition to the recipe but adds a delicious fruity flavor to the dessert and makes it perfect for summer with its seasonality.

Tips for the Perfect Lemon Peach Posset:

Lemon posset is wonderfully straightforward, but a few simple tips will guarantee a silky smooth result every time.

Use full-fat heavy cream. The fat content is essential for achieving that rich texture and proper set.
Simmer the cream and sugar for the full amount of time. This helps the mixture reduce slightly and creates the perfect consistency.
Always use freshly squeezed lemon juice. Fresh lemons provide the right balance of acidity and flavour.
Add the lemon juice after removing the cream from the heat. This helps preserve the bright citrus flavour while allowing the mixture to set properly.
Chill the posset for at least 4 hours, though overnight is even better if you have the time.
If you’re entertaining, make it a day ahead. It’s one of those desserts that tastes just as good, if not better, after resting in the fridge.
Swap the peaches for nectarines, apricots or mango. I have also made this recipe with raspberries, but strain out the mixture to remove the seeds.

Frequently Asked Questions:

Why does posset set? Why Does it set without gelatin?

The acidity in the lemon juice reacts with the proteins in the cream, naturally thickening the mixture as it chills.

Can lemon posset be frozen?

While lemon posset can be frozen, I don’t usually recommend it. The creamy texture that makes this dessert so special can change once thawed, becoming slightly grainy or separated. For the best texture and flavour, it’s best enjoyed fresh from the refrigerator.

Is lemon posset the same as lemon pudding?

Not quite. While both are creamy lemon desserts, lemon posset is traditionally made with just cream, sugar, and lemon juice. It sets naturally thanks to the acidity of the lemon, creating a rich and silky texture without eggs, cornstarch, or gelatin. Lemon pudding, on the other hand, often contains eggs, milk, or a thickening agent and is usually softer and more custard-like in texture. Lemon posset is richer, smoother, and has a brighter, more pronounced lemon flavour.

Can I use bottled lemon juice?

Fresh lemon juice is highly recommended. Bottled varieties can have a slightly different acidity level and flavour.

Can I use lime instead of lemon?

Yes. Lime creates a slightly sharper, more tropical version of the dessert and works wonderfully. But lemon and peaches work better in this dessert.

My posset didn’t set. What went wrong?

This usually happens if the cream wasn’t simmered long enough or if there wasn’t enough citrus juice added to the mixture.

Serving Suggestions

One of the things I love most about posset is how versatile it is. Its rich, creamy texture and bright citrus flavour pair beautifully with a variety of toppings, whether you’re keeping things simple or dressing it up for a special occasion.

For a classic finish, top the posset with a little freshly grated lemon zest. It enhances the citrus flavour while adding a pop of colour. Fresh berries such as raspberries, strawberries, or blueberries also work beautifully, bringing a touch of sweetness and freshness to every spoonful.

If you enjoy a bit of texture, serve the posset with crushed shortbread biscuits, buttery cookies, or a sprinkle of toasted pistachios. The contrast between the silky cream and the crunchy topping makes each bite even more satisfying. For an elegant dinner-party dessert, layer the posset with a spoonful of berry compote or serve it alongside crisp almond biscuits. You can also garnish with edible flowers for a simple but beautiful presentation.

Whether served in small glasses, ramekins, or vintage dessert bowls, lemon posset is best enjoyed well chilled and shared with good company. Set the possets in halved and hollowed peaches to create an edible cup.

Storage and Make-Ahead Tips? How long does posset last in the fridge? Can I make posset ahead of time?

Posset stores beautifully, making it a great dessert for planning ahead. Keep it covered in the refrigerator for up to 3 days. For the freshest flavour and texture, add any toppings just before serving.

If you’re preparing it for a gathering, make the posset the day before and let it chill overnight. The texture only improves as it rests, giving you one less thing to think about on the day of serving.

Yes you can make lemon possets ahead, in fact, it’s one of the best make-ahead desserts since it needs several hours to chill and set properly.
