How to make Lemon Posset

Lemon posset is a classic British dessert that is beautifully simple and wonderfully refined. Made with cream, sugar, and fresh lemon juice, it sets into a smooth custard-like dessert without eggs or gelatin. The flavor is bright, creamy, and gently tangy, making it perfect for dinner parties or an easy make-ahead treat.

1. 1Add the heavy cream, sugar, lemon zest, and salt to a saucepan.
2. 2Warm over medium heat, stirring until the sugar dissolves.
3. 3Bring the mixture to a gentle simmer and cook for 3 minutes, stirring often.
4. 4Remove the saucepan from the heat.
5. 5Stir in the fresh lemon juice and vanilla extract.
6. 6Let the mixture sit for 5 minutes so the lemon flavor infuses.
7. 7Strain through a fine mesh sieve into a jug.
8. 8Pour the posset into small glasses or ramekins.
9. 9Refrigerate for at least 4 hours, or until fully set.
10. 10Serve chilled with fresh berries and shortbread cookies.
