Yes. Parchment prevents sticking and makes transfer easy. A preheated baking sheet underneath helps crisp the bottom.

Yes, but heat-up differs from metal. Glass can give a paler bottom unless you bake on a lower rack or preheat a baking stone. Ceramic holds heat well; you may need to extend time slightly for a crisp base.

Yes. Egg wash gives colour and shine. Brush lightly so you do not seal the edges you want to flake apart; sometimes only the visible top is washed.

Yes. Cut two rounds, cut a smaller circle from the centre of one stack layer, egg-wash and stack, then bake so the centre rises as a lid. Fill after baking so the case stays crisp.

Yes. Many pies use shortcrust base and puff lid for lift and looks. Vent the lid so steam escapes and brush with egg wash for colour.

Often you dock the base lightly and may use foil without heavy pie weights, because weights can stop puffing where you want lift. For wet fillings, partial baking to dry the base is common; techniques differ from shortcrust.

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.

Docking with a fork helps steam escape and can reduce doming. For fully blind-baked shells you usually dock, line with paper and baking beans, then bake; some bakers dock again after removing beans if the base puffs.

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.

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.

An egg wash on exposed edges promotes an even golden colour and can help seal a top crust to a bottom. It is optional on blind-baked tart edges but improves appearance.

Scoring controls where steam splits the surface and can look decorative. Do not cut all the way through stacked layers unless the recipe intends it.

Yes. Warm puff loses the distinct layers of butter or margarine and may bake unevenly. If it softens while shaping, chill it on the tray before baking.

Yes. Cold fat and cool hands (or a cool kitchen) help the fat stay in small pieces until baking, which gives a tender, flaky short texture. If the dough feels greasy or warm, chill it before rolling.

You line the pastry with parchment and fill with ceramic beans, dried pulses, or rice to weigh the sides down so they do not slump. Remove the paper and weights partway through so the base can dry and colour.

A hot oven—often around 200°C or higher for the first part of baking—helps rapid steam generation. Some recipes reduce heat partway through so the inside cooks without burning the top.

Many recipes use around 180–200°C fan-adjusted equivalents, depending on your oven. Start with a hotter stage if you want extra colour, then reduce if the edges brown too fast. Always follow your recipe’s fan or conventional settings.

Opening the door too soon, underbaking, or very humid filling added immediately can soften structure. Bake until deeply golden and cool slightly on a rack before filling.

Common causes are warm dough, old pastry, crushed layers from heavy rolling, or opening the oven early so steam escapes. Bake at a high enough temperature initially so water in the fat turns to steam and lifts the layers.

Shrinkage usually comes from gluten that was overworked, dough that was not rested, or the pastry being stretched into the tin instead of lifted and eased in. Chill the lined tin before baking, avoid stretching, and rest the dough after rolling so gluten relaxes.

Uneven thickness, hot spots in the oven, or trays crowded together cause uneven browning. Rotate the tray halfway through if your oven needs it and leave space for air circulation.

Wet fillings without pre-baking or docking, or insufficient oven heat on the base, can cause sogginess. Bake on a preheated tray, use a perforated tin or baking stone if needed, and consider blind baking or a drier filling layer.
