Lemon Posset Recipe

Lemon Posset Recipe – creamy, flavorful and satisfying dessert – a must try in summer 2023. The lemon dessert trend is gaining popularity all over the internet and I can’t hide my satisfaction. I’m a huge lemon dessert lover and very happy to share some amazing recipes with you. The combination of sweet and tangy is so good, and this is what most lemon desserts represent. The final result is a creamy dessert with a texture similar to Panna Cotta.

This creamy dessert is made with just 3 ingredients in under 15 minutes of cooking time (you still have to wait for it to set and thicken, while cooling down).

Serve in lemon shells (lemon cups), like in this Lemon Creme Brûlée, shot glasses or small bowls.

What is Lemon Posset?

Lemon Posset is a dessert, that originates from the United Kingdom. 

A posset was originally a British drink made of hot curdled milk and then flavored with wine, ale or spice. Certain sources provide information of Posset Desserts made with egg yolks. 

The posset recipe I’m sharing with you today is a spin on this classic dessert.

It is basically “curdled cream”. A creamy custard like pudding, made with heavy cream, sweetened with sugar, flavored with lemon zest and “curdled” with lemon juice. Make sure you strain the mixture to ensure it is extra smooth and creamy. There is no cornstarch used to “thicken” the dessert.

The lemon juice causes a reaction with the cream resulting in it setting up. 

You may know that pastry making and desserts in general are my passion, so “Possets” are new to me. I’ve seen them as components of sophisticated desserts at nice restaurants here in Europe.

How to make Lemon Posset Dessert?


  • Heavy Cream (or double cream, if you have access to it). I’d say that “Double Cream” is the better option, but I rarely have access to it.  Double cream is a British term for heavy cream in the United States, but they are not quite the same. Double cream is a little thicker than regular whipping cream. It contains about 48% butterfat. Double cream is very rich and you can over whip it and get it too thick. 
  • Sugar (I recommend fine caster sugar, but any sugar will work). Erythritol can be substituted for sugar, if necessary.
  • Whole lemons for zesting and juicing. I used Eureka lemons, but Meyer lemons will work, too. You need about 2 lemons in the recipe (since 1 lemon yields about 40-45 ml of juice).

The recipe is unbelievably simple to make. Almost no cooking involved. All you need to do is get your ingredients easy.

Heat the cream, lemon zest and sweetener on the stove top, until it starts to bubble. Remove from heat. Add in the the lemon juice and stir.

The mixture will start to thicken, once it starts cooling down.

Strain into lemon shells or serving cups. Refrigerate for at least 1 hour.

Recipe tips:

  • Use good quality ingredients – real heavy cream, caster sugar if possible, fresh lemons.
  • Do not overheat the heavy cream, just heating it to the point, where fine bubbles appear on top of it is enough.
  • Make sure you wash the whole lemons very well with a sponge and detergent, then rinse and pat dry. This will remove the waxy layer, that lemon shells have been treated with, to prevent easy spoiling. The layer also brings extra bitterness, if not washed out. This wax helps preserve the lemons and keep their rinds clear of any germs or insects while they’re transported and sit in the store’s produce bins.
  • Lemon Shells – make sure the lemons you use are fresh. How to make these? Cur lemons in half lengthwise. Using a spoon or a melon balled scoop out the flesh, leaving the peel to form a cup. It may be a little messy.
  • How to store lemon posset dessert? If you make it in glass cups or bowls, store covered in the fridge for up to 5 days. If you happen to make it in lemon shells (lemons cut in half lengthwise and the flash scooped out), you can store in the fridge for up to 2 days, because the dessert sitting in lemon peels, may start to absorb too mush lemon flavor and also the shells may get too dry or even spoiled.
