Lemon posset is a chilled British dessert made by thickening cream with sugar and lemon juice. It has a smooth, rich texture and is usually served in small glasses or bowls, often with berries or biscuits.
Lemon posset may stay runny if the cream mixture was not heated enough, the cream was too low in fat, or the lemon juice was not measured correctly. Chill it thoroughly; for the next batch, use full-fat cream and follow the heating steps closely.
Yes, bottled lemon juice can work in lemon posset, but freshly squeezed juice usually gives a brighter flavour. Add the juice after heating the cream and sugar, and avoid using sweetened or concentrated lemon drink.
No, traditional lemon posset contains neither eggs nor gelatin. Its simple base is cream, sugar and lemon juice; the acidity of the lemon helps the heated cream thicken as it cools.
To keep lemon posset smooth, take the heated cream and sugar off the heat before stirring in the lemon juice. Mix gently and strain the mixture if needed, then pour it into serving dishes and chill.
Lemon posset is most reliable with high-fat cream, such as double cream or heavy cream. Single cream or milk has less fat and may not thicken properly, so swapping it in can leave the dessert loose.
Lemon posset keeps for about two to three days in the refrigerator when covered. Store it chilled in its serving dishes, and add fresh fruit or crunchy toppings shortly before serving.
Freezing lemon posset is not recommended because thawing can make its creamy texture split or turn grainy. It is better to prepare it ahead, keep it covered in the refrigerator, and serve it chilled.
Lemon posset pairs well with fresh berries, shortbread, or crisp biscuits. Their tartness or crunch balances the dessert’s rich texture; add them just before serving so the fruit stays fresh and the biscuits do not soften.
No. Lemon posset thickens when lemon juice reacts with heated cream, while panna cotta is typically set with gelatin. Posset has a sharper citrus flavour and a creamy spoonable texture; panna cotta is usually more softly wobbly.

Lemon posset is a British chilled dessert made with cream, sugar and lemon juice. The lemon’s acidity thickens the cream, giving the mixture a smooth, spoonable set without needing gelatine. It is usually served in small glasses or bowls, often after a meal.
Its texture is rich and silky, with a sweet-tart citrus flavour. In Britain, it is a familiar make-ahead pudding for dinners and special occasions; elsewhere, it works just as well as a simple finish to a meal or alongside tea or coffee. It is energy-dense, with most of its calories coming from cream and sugar. Keep the serving modest and pair it with fresh berries for a brighter, less heavy contrast.
