The peach is a stone fruit related to the plum, cherry, almond, apricot, and nectarine. Peach flesh tastes and feels somewhat like mango flesh. Freestone peaches have flesh that separates easily from the pit. Cling peaches have flesh that clings to the pit. Cling peaches taste a bit better, but might not be worth the trouble. Peaches are fuzzy on the outside; some people will want to peel off the skin.
Choose peaches with a strong and pleasant smell. Peaches will soften if left around, but will not gain a nice ripe taste and smell. Do not refrigerate peaches.
