Help with PIE! Top crust balloons up...
As the subject-line indicates, I've been having a problem with the pies I bake. The top crust balloons up during baking. So when the pie cools, the top crust is not adhered to the filling - it breaks down when you slice the pie.
I do use a 'vent'. I typically cut a 1/2-inch circle in the centre. Too small? Too few? It does seem to allow steam to escape, but... the problem persists.
If anyone has any tips for preventing the undesirable pie balloons, let me know!
I had that problem once, so changed my recipe for the pie crust to one that had a bit more shortening. The top crust then layed down on the apples and conformed to the filling. Here are a couple places you can look:
On the one, "Joy of Baking" start reading just above the Pate Brisee section. Sentence begins with..."Once you have sliced the apples in hand......"
It's not actually the top ballooning as the top setting while the fresh fruit hasn't broken down and settled yet.
Depending on what kind of fruit you're using (apples for example), you can cook them down a bit in a saute pan before filling and baking. Just be sure to cool the fruit before filling.
