In a medium saucepan, combine 2 cups of heavy cream and ¾ cup of granulated sugar over medium heat. Stir gently as the mixture warms, ensuring that the sugar fully dissolves.

Once the sugar has dissolved and the cream is hot, remove the saucepan from heat. Stir in ½ cup of fresh lemon juice and the zest of 1 lemon. Mix well until thoroughly combined.

Grab your individual serving glasses or ramekins and carefully pour the Lemon Posset mixture into each one, leaving a little space at the top.

Place the filled glasses in the refrigerator for at least 4 hours, or until the Lemon Possets are fully set.

Once set, remove your Lemon Possets from the refrigerator and consider garnishing them with fresh berries or mint leaves before serving.
