The short answer is that homemade pie dough can last for about 3 to 5 days in the fridge. Yep, you read that right - just a few short days! But, if you're using store-bought pie dough, the shelf life is usually a bit longer, around 5 to 7 days. It's like the difference between a freshly baked cookie and a store-bought one - both are delicious, but one is definitely more fragile!
Now, you might be wondering why the difference? Well, it all comes down to the ingredients and how they're mixed together. Homemade pie dough typically contains more water and yogurt, which can make it more prone to bacteria growth. On the other hand, store-bought pie dough usually has more preservatives to extend its shelf life.
