What is Lemon Posset?

A traditional British Lemon Posset is made with cream, lemons and sugar, heated together and chilled to set for a silky smooth finish. It’s often served with a shortbread biscuit (cookie) on the side for a little crunch.

It’s a perfect dessert when cooking a special meal, hosting a dinner party or barbecue, because you can make them ahead of time and keep them in the fridge until it’s time to serve.

They’re also really delicious – fresh, citrusy and sweet, while creamy at the same time.

Lemon Posset has evolved from what it was centuries ago, when it was once a medicinal drink made up of milk and alcohol, curdled together with spices such as nutmeg and cinnamon.


Lemon Posset Ingredients

The three ingredients that make up a Lemon Posset recipe laid out on a white counter - lemons, sugar and cream.
  • Double cream – This is also known as ‘heavy cream’ outside of the UK. Single cream won’t work with this as we need the high fat content that helps the dessert to set.
  • Caster sugar – This is finer than granulated sugar, and if you’re outside of the UK may be called superfine, bar or baker’s sugar.
  • Lemons – We’re using the zest for flavour and decoration, and the juice for flavour too.

How to make Lemon Posset

1. Zest 1 of the lemons for decoration onto a small plate and set aside.

Cream, sugar and lemon zest in a saucepan.

Why hasn’t my Lemon Posset set?

    Outstanding recipe, Sarah! I made this ahead of time when I was hosting a birthday dinner party, and they went down so well. It was great to dish up a homemade dessert but one that I could make the day before so there was no stress.
