The pastry is Pâte Sucrée and the filling a mixture of eggs, sugar, double cream and, of course, lemons. However, this basic formula can be adapted to ring the changes. The pastry should be sweet, but can be varied from sweet shortcrust to hazelnut pastry, almond pastry or even chocolate pastry, which is good with an orange tart.
Some suggestions for fillings are lime, lime and ginger, orange and lemon, chocolate and orange, passion fruit and lemon, raspberry and lemon and even pink grapefruit. If fewer lemons are used, the amount of sugar can be reduced. Also the cream can be replaced by Greek yoghurt, for a filling which is a little lower in calories.
