Another version of lemon bar would be lemon tart. The tart filling made from the juice of 2 lemons, flour, eggs, sugar, butter and vanilla are poured into the tart pastry shell and baked for 20 to 25 minutes. You can use any recipe to make pastry shell, but basically it is made of cold butter, flour, egg yolk and a little cold water.
The pastry can be decorated with candied lemon slices. The resulting pastry is loaded with bright lemony flavor that most anybody will enjoy.
