Now there's a way to tell: a clever new method I'm calling the Taste Test (patent pending).
1. Buy the taffy apple. Retailers get upset if you skip this step.
2. Examine it closely. Unlike beer, gourmet taffy apples have no "born on" date, so you've got to rely on your senses. Remove the wrapper. Sniff all over the taffy apple the way a dog would.
3. Take a big bite.
4. And another.
5. And another.
6. If you haven't hit a rotten spot yet, the taffy apple is probably fresh. Finish it off.
7. If you do hit a rotten spot, eat around it and keep going.
