Do I need to blind bake shortcrust pastry for every tart?
No. Blind bake when the filling is very wet, sets quickly, or does not need long in the oven—classic for custard, lemon curd, or no-bake-style fillings. For fillings that bake a long time at a similar temperature to the pastry, you can sometimes bake raw shell and filling together, though blind baking still helps avoid a soggy base.
How do I stop a soggy bottom on a shortcrust tart?
Blind bake until the base is dry and lightly coloured, seal with a thin layer of egg white or chocolate if appropriate, brush hot jam on fruit tarts, or sprinkle a little ground nuts or semolina on the base. A metal tin and a hot oven for the initial bake also help crisp the underside.
How thick should I roll shortcrust for a tart case?
About 3–4 mm is typical for a standard tart—thin enough to cook through without being brittle, thick enough to handle. Thinner shells bake faster; very thick bases can be doughy in the centre.
How do I know when blind-baked shortcrust is done?
The pastry should look dry, feel crisp to the touch, and be an even golden colour—especially the base. Underbaked shells stay pale and soft and will sog with wet filling.
