Sign #2: When You Tap on an Apple and You Hear Something
A gorgeous yet mealy apple is one of life's greatest small disappointments—and puzzles: How can something so perfect-looking taste so awful? While it's impossible to guarantee a crisp, juicy fruit (you can forget looks; misshapen apples can taste just fine), there's one indicator you can usually rely on: The sound you hear when you tap the side of the apple with a finger. Good apples should sound hollow; bad ones will often sound dense. But if you do wind up with a mealy apple, one way to rescue it is to turn it into applesauce.
