We are already on our third recipe in this Apple A Day series and I just realized we never really talked about choosing a good apple.

You know the phrase about one bad apple spoiling the bunch. That can be interpreted very broadly and metaphorically if you like. But it's also a literal truism when it comes to actual apples. Ripe apples emit ethylene gas as they age and ethylene gas is a party drug to apples. One whiff of the stuff and perfectly fine apples think the party is ending and they hasten their own ripening process, leading quite quickly to the rotting process. Chilling apples can slow the party down, so it is one fruit I do keep in the fridge. But chilled or no, apples should not be kept in a bag or a pile. They are less likely to pass (ethylene) gas onto their neighbors if they are stored in a single layer.

Since bad apples can be so detrimental to good apples, I usually start my choosing process by eliminating the bad apples.
