Flat out flavorful. Donut Peaches™ are also called Saturn or Flat Peaches because of their saucer shape. Saturn Peaches have white flesh that is low in acid allowing them to be deliciously sweet when they are firm and crunchy AND when they ripen longer to become soft and juicy. You too can learn how to “properly” eat a Saturn Peach – just like the ancient kings of China who ate white-flesh Flat Peaches, not unlike today’s modern varieties, without soiling their beards. STEP 1: Grab one between your thumb and index-finger STEP 2: Munch your way around the small pit that will remain between your fingers.
