Low-carb lemon meringue pies are a wonderful easy pie that can be made hot or cold, and prepared in advance.
To serve hot, make the crumble base and lemon curd as shown. Layer the base and the curd in individual heatproof jars and cook the meringue directly on top of the sugar-free lemon meringue pie.
To serve cold, prepare the 3 layers as shown then construct the sugar-free lemon meringue pies and keep covered in the fridge until ready to serve. This way they can be made a day ahead.
