This pastry will have a slightly uneven edge around the rim of the tin, resulting in a tart that looks rustic and home-made, which is what we aim for at Bourke Street Bakery. If you are after a perfectly even effect, this is not the pastry to use—this dough has water in it, which means it will shrink as the water evaporates during baking; the following method is to help counteract this shrinkage.
The number of tarts you end up with will vary, depending on how thinly the pastry is rolled. The pastry can be frozen for up to 2 months, so it makes sense to line all the shells with foil (ready to blind-bake), store them in the freezer, then blind-bake them as you need them. You do not need to thaw them first.
