How Can You Tell If Apple Pie Is Bad?
There are a few signs that indicate that an apple pie has gone bad. The most obvious is a sour or rancid smell. The crust may also appear moldy, discolored or soggy. Additionally, if the filling has watery or slimy consistency, it might have gone bad. Mold growth is another key indicator, and if any mold is present on the crust or filling, the pie should be discarded immediately. If the pie has been stored in the fridge for more than four days, it is best to err on the side of caution and throw it away, even if it appears to be visually fine.
