Most American children eat potatoes. But many children don't know what of the potato is the best for food. Take a knife and cut from the middle of the potato a piece as thin as paper. Hold the piece between your eyes and light. You will see that the potato has skin (皮), an outside rim (边缘) and an inside part. The outside rim which is right under the skin of the potato, is the most valuable part of all. But this is often thrown away with the skin. Even the skin itself is better for food than the inside. When eating a cooked potato, if you choose the inside and leave the outside, you are throwing the best part of it. If you can't eat the whole potato, eating the outside rim and leaving the inside will do.
