- Not blind-baked
Raw pastry under a moist filling never dries out properly.
Next time: Blind-bake the base
- Too little heat from below
In the middle of the oven, the base gets too little heat.
Next time: Lowest shelf · Bake on a preheated tray
- Very runny filling
A lot of juice softens any base.
Next time: Bind fruit with a little starch or ground nuts · Brush the base with egg and bake it briefly
