Lemon Posset Recipe You’ll Make On Repeat

Last updated: May 24, 2026

This lemon posset is a rich, silky British dessert made with just a few simple ingredients, but it tastes elegant enough for dinner parties and special occasions. It’s a great recipe to keep on hand when you want something creamy, tangy, and surprisingly easy to make.

Ingredients List

For the lemon posset

• 2 cups heavy cream
• 3/4 cup granulated sugar
• 5 tablespoons fresh lemon juice
• 1 tablespoon finely grated lemon zest
• 1 teaspoon vanilla extract
• Pinch of salt

Optional toppings

• Fresh berries
• Extra lemon zest
• Shortbread cookies
• Mint leaves

Ingredient Notes

Heavy cream

Use full-fat heavy cream for the classic thick, velvety texture. Lower-fat cream will not set as well and can leave the lemon posset too loose.

Lemon juice

Fresh lemon juice is essential here because it gives the dessert its bright flavor and also helps it thicken naturally. Bottled juice can taste flat and slightly harsh.

Lemon zest

Zest adds a deeper citrus flavor without extra liquid. It gives the finished dessert a fresher, more fragrant taste.

Sugar

Sugar balances the sharpness of the lemon and helps create that smooth, custard-like finish. Reducing it too much can make the dessert taste overly tart.

Vanilla extract

This is optional but highly recommended because it softens the citrus edge and rounds out the flavor nicely.

Pro Tips For Best Results

• Simmer the cream and sugar gently rather than boiling aggressively, or the mixture can reduce too quickly.
• Stir the sugar until fully dissolved so the finished lemon posset stays smooth, not grainy.
• Add the lemon juice after removing the pan from direct heat to keep the flavor bright and fresh.
• Chill the posset long enough to fully set; a rushed chill time can leave it too soft in the center.
• Strain the mixture before pouring if you want an extra silky, restaurant-style texture.
• Serve in small glasses or ramekins because this dessert is rich and satisfying in modest portions.

Method

1. Prepare your serving dishes

Set out 4 to 6 small ramekins, dessert glasses, or teacups on a tray or plate. Having them ready makes it easier to pour the lemon posset while the mixture is still warm and fluid.

2. Add the cream, sugar, and salt to a saucepan

Pour the heavy cream into a medium saucepan, then add the sugar and a pinch of salt. The mixture should look pale and creamy with the sugar sitting visibly at the bottom before heating.

3. Heat the mixture gently

Place the saucepan over medium heat and stir steadily until the sugar fully dissolves. You’ll know it is ready when the liquid looks glossy and completely smooth, with no sandy bits on the spoon.

4. Bring to a gentle boil

Let the mixture come to a gentle boil, then cook for about 3 minutes while stirring often. You want to see small, steady bubbles around the surface, not a wild rolling boil.

5. Remove from the heat

Take the pan off the heat once the cream mixture looks slightly thicker and silky. This step matters because overcooking can make the final texture heavier than it should be.

6. Stir in the lemon juice, zest, and vanilla

Add the fresh lemon juice, lemon zest, and vanilla extract, then stir until fully combined. The mixture should look smooth, lightly thickened, and fragrant with a bright citrus aroma.

7. Let it sit briefly

Leave the mixture to rest for 5 minutes in the pan. This short pause helps the bubbles settle so the finished lemon posset looks smoother on top.

8. Strain for a silkier finish

Pour the mixture through a fine-mesh sieve into a jug or bowl if you want the smoothest possible texture. After straining, it should look glossy, pale yellow, and free from zest strands or foam.

9. Pour into ramekins or glasses

Carefully divide the mixture between your serving dishes. Fill each one evenly, leaving a little room at the top for garnish, and look for a smooth, level surface.

10. Cool at room temperature

Let the lemon posset cool for about 20 to 30 minutes before chilling. As it cools, the surface should begin to look slightly settled rather than loose and bubbly.

11. Chill until set

Transfer the desserts to the fridge and chill for at least 4 hours, or until fully set. When ready, the lemon posset should have a soft wobble in the center but hold its shape when you tilt the ramekin.

12. Garnish and serve

Top with berries, extra zest, mint, or a shortbread cookie just before serving. The finished dessert should look creamy, smooth, and lightly glossy with a fresh citrus scent.

Variations You Can Try

• Lemon and lime posset: Replace 1 to 2 tablespoons of lemon juice with fresh lime juice for a sharper citrus finish.
• Berry lemon posset: Spoon a little raspberry or blueberry compote into the bottom of each glass before pouring in the mixture.
• Vanilla bean version: Use vanilla bean paste instead of extract for a slightly warmer, more luxurious flavor.
• Orange-lemon twist: Add a little orange zest along with the lemon zest for a softer citrus profile.
• Dairy-free style: Try a full-fat coconut cream version, though the set and flavor will be different from classic lemon posset.
• Lavender lemon posset: Infuse the cream with a very small pinch of culinary lavender, then strain before adding the lemon juice.

Serving Suggestions

• Serve with shortbread cookies for a classic pairing and a buttery contrast to the tangy cream.
• Add fresh raspberries or blueberries for color and a juicy, tart finish.
• Make it for dinner parties, spring brunches, or summer gatherings when you want an easy make-ahead dessert.
• Spoon into small glass jars or pretty teacups for a more elegant presentation.
• Finish with extra lemon zest and mint for a fresh, clean look that photographs beautifully.

Conclusion

This lemon posset works so well because it turns a handful of basic ingredients into a dessert that feels both simple and special. Once you make it once, it’s the kind of recipe you’ll come back to again and again, whether you keep it classic or add your own twist.

Key Takeaways

• Lemon posset uses a short ingredient list but delivers a rich, silky texture.
• Fresh lemon juice is essential for both flavor and proper setting.
• It’s an easy make-ahead dessert that feels elegant with very little effort.
• Small serving dishes work best because the dessert is rich and satisfying.
• You can customize it with berries, herbs, cookies, or other citrus flavors.
• A full chill time is the key to the perfect soft-set finish.

How To Store & Make Ahead

Store lemon posset covered in the fridge for up to 3 days. Keep toppings off until just before serving so the surface stays fresh and smooth.

Freezing is not ideal because the texture can become grainy or separate after thawing. This dessert is best enjoyed freshly chilled.

To make ahead, prepare it the day before and chill overnight. That actually improves the texture and makes it perfect for entertaining.

There is no need to reheat lemon posset since it is served cold. Just take it out of the fridge a few minutes before serving if you want a slightly softer texture.

FAQs

How do you know when lemon posset is set?

Lemon posset is set when it looks firm around the edges with a slight wobble in the center. It should hold its shape when gently tilted but still look soft and creamy.

Can I make lemon posset without zest?

Yes, you can make lemon posset without zest, but the flavor will be slightly less fresh and aromatic. The zest adds extra citrus depth without making the dessert more tart.

Why didn’t my lemon posset set properly?

The most common reasons are not simmering the cream mixture long enough, using cream with too little fat, or not chilling it long enough. Fresh lemon juice also matters because it helps the dessert thicken naturally.

Can I make lemon posset in advance?

Yes, lemon posset is one of the best make-ahead desserts. You can make it up to a day ahead, keep it chilled, and garnish just before serving.
