# How to Make:
01 - Halve the 6 large lemons lengthwise. Carefully juice and scoop out the flesh, preserving the shells. Trim a small slice off the bottom of each shell to ensure they stand upright. Refrigerate the shells until needed.
02 - In a medium saucepan, combine heavy cream, caster sugar, and lemon zest. Heat over medium heat, stirring until the sugar dissolves. Allow to simmer gently for 3 minutes without boiling over, then remove from heat.
03 - Stir in the freshly squeezed lemon juice; the mixture will thicken slightly. Let it cool for 10 minutes, then strain to remove the zest for a smooth texture.
04 - Carefully pour the warm lemon cream mixture into the prepared lemon shells, filling them close to the rim.
05 - Refrigerate the filled lemon shells for at least 3 hours, allowing the mixture to set properly.
06 - Just before serving, sprinkle about 1 teaspoon of caster sugar evenly on each posset. Use a kitchen blowtorch to caramelize the sugar until crisp. Let it harden for 2–3 minutes before serving.
