# How to Make It:
01 - Halve 6 large lemons lengthwise. Juice and carefully scoop out the flesh, preserving the shells. Trim a thin slice off the bottom so shells stand upright. Refrigerate shells.
02 - Combine heavy cream, sugar, and lemon zest in a medium saucepan. Heat over medium until it gently boils, stirring until sugar dissolves. Simmer for 3 minutes without boiling over, then remove from heat.
03 - Stir in freshly squeezed lemon juice. Mixture will thicken slightly. Let cool 10 minutes, then strain to remove zest for a smooth texture.
04 - Carefully pour the warm cream mixture into prepared lemon shells, filling close to the rim.
05 - Place filled shells in the refrigerator for at least 3 hours until the mixture sets firmly.
06 - Just before serving, evenly sprinkle about 1 teaspoon caster sugar over each filled shell. Use a kitchen blowtorch to caramelize sugar until crisp. Allow topping to harden for 2–3 minutes before serving.
