Most people cannot tell the difference between Coke and Pepsi in a blindfold taste test. (Blindfold yourself and try it before you tell me you're the exception. The key word if blindfold.)
I have always felt the same way about cooked carrots and cooked sweet potatoes. They look the same and they taste the same -- and if you melt marshmallows on cooked carrots they're exactly the same.
Ditto for chicken salad and tuna salad.
