“You throw away the outside and keep the inside, then you eat the outside and throw away the inside”

“You throw away my outside, you cook my inside. Then you eat my outside and you throw away my inside. What am I?” is a riddle that has been printed in many images. The answer is “corn.” The outer husk is thrown away, the corn kernels are eaten, and then the inner cob is thrown away.
 
“You throw away the outside, cook the inside, eat the outside and throw away the inside? What is it? An ear of corn” was printed in the Osmond (NE) Republican on January 18, 1950. “What vegetable do you throw away the outside, cook the inside, eat the outside of the inside, then throw away the inside? Corn on the cob” was printed in the Rochester (NY) Democrat and Chronicle and many other newspapers on October 6, 1958.
