Why I Love This Recipe

The first time I made lemon posset, I couldn’t believe how simple it was. I kept checking the recipe because it seemed impossible that cream, sugar, and lemon could turn into such a smooth dessert. After chilling overnight, the texture was rich and creamy, almost like a cross between pudding and cheesecake filling. Since then, it has become one of my favorite make-ahead desserts.

Why This Recipe Works (Quick Science)

Heavy cream contains enough fat to create a rich texture.
Boiling the cream and sugar helps dissolve the sugar completely.
The acid in lemon juice reacts with the cream proteins.
As the mixture chills, it naturally thickens without gelatin.
The result is a silky dessert with a smooth spoonable texture.

Pro Tips

Use fresh lemons for the best flavor.
Do not reduce the cream amount.
Let the mixture cool slightly before pouring into bowls.
Chill for at least 4 hours for the perfect texture.
Finely grate only the yellow part of the lemon peel.

Substitutions and Variations

Use orange juice and orange zest for an orange version.
Add a little vanilla extract for extra flavor.
Top with fresh berries before serving.
Add crushed shortbread cookies on top.
Mix in a little lavender for a floral twist.

Make Ahead Tips

Make up to 2 days ahead.
