To cool a pie quickly you place it in the fridge.
However before placing the hot and freshly baked pie in the fridge the pie needs at least 30 minutes to cool at room temperature.
Don't place the freshly baked pie directly into the fridge while it's hot.
Wait at least 30 minutes for the pie to cool at room temperature and then place the cooled down pie into the fridge to cool further.
Cool the pies at room temperature for only 30 minutes after you take them out of the oven.
Put the pies or pie in the refrigerator to complete cooling and to keep them cold.
Keep pies in the refrigerator at 41°F or colder, except during the time they are being served.
Some types of pies should be cooled a bit longer than others.
Fruit pies should cool at least four hours before slicing; custard pies should cool for two hours before serving or being refrigerated.
Pie must cool completely.
The hardest part of making a pie is waiting for it to cool.
So never (ever) slice into a hot pie!
The filling needs time to set as it comes to room temperature.
