It has a pastry shell with a lemon flavored filling.

In the United Kingdom, lemon tart consists of a pastry case (often made in a fluted tart tin) containing a baked lemon custard (usually composed of eggs, sugar, lemon juice and cream).

Usually recipes include blind-baking before adding the custard.

Sometimes, the tart is dusted with icing sugar prior to serving.

[1][2][3][4] Alternatively, the lemon filling can be cooked in a saucepan and then added to the baked pastry case.
