Making Lemon Posset can be straightforward if you follow these simple steps:

1. Heat Cream and Sugar: In a medium saucepan, combine the heavy cream and granulated sugar. Place over medium heat.
2. Dissolve Sugar: Stir the mixture gently until the sugar fully dissolves. Bring it to a gentle simmer, stirring occasionally.
3. Simmer the Mixture: Allow the mixture to simmer for about 3 minutes, ensuring it does not boil vigorously.
4. Remove from Heat: Take the saucepan off the heat and let it cool for a minute.
5. Add Lemon Juice: Stir in the fresh lemon juice and mix thoroughly until well combined. The cream will begin to thicken.
6. Pour into Molds: Carefully pour the mixture into individual serving cups or ramekins.
7. Chill: Cover with plastic wrap and refrigerate for at least 4 hours, or overnight for the best results.
8. Serve: Once set, garnish with additional lemon zest, berries, or a sprig of mint before serving.
