Potatoes: in all shapes, sizes, varieties

Potatoes are just big and brown on the outside and white on the inside, right?

Wrong.

"There are hundreds of varieties of potatoes out there,"said Meredith Myers, public relations manager for the U.S. Potato Board.

Most people recognize the basic categories that include russets, red skins and yellows and golds.

But what about the blues and purples?

Yes, blues and purples.

"More people are asking for our purple potatoes,"said Steve Carpenter, of Jack-O-Lantern Farms in Muscle Shoals. It's one of several varieties of potatoes he offers for sale at his market.
