Lemon Tart – Tarte au Citron

5/5 - (4 votes)

As many of you will already know I really enjoy anything that has a lemon flavour.  So this Lemon Tart, or Tarte au Citron is a surefire winner for me.

The tart has a lovely crisp biscuit-like tart shell and is then filled with a thick lemon custard that sets up well in the fridge to deliver a really nice tart which slices well and tastes fantastic.

Although the recipe takes a while, as I like to thoroughly chill the pastry dough, it is actually quite simple to make.  It does require attention all the while though, when making the lemon custard, as it has to be whisked constantly to ensure that the eggs don’t scramble as they are cooked.

But having made the tart shell and the custard it only remains to pour the the filling into the shell and then to allow it to set up, in the fridge before serving.

The time taken is well worth the wait as my lemon tart tasted so good, sharp but sweet and with a lovely crunch to the pastry.

Pies and Tarts are a favourite of mine I particularly like Fresh Fruit & Mascarpone Tart.
