Bring a large pot of water to a boil. Set up an ice bath of water and ice in a large bowl. Cut a small “X” on the bottom of each peach. Two or three at a time, lower peaches into the boiling water using a slotted spoon. Let peaches boil until the skins start to curl back at the “X” mark, 30 seconds to 1 minute for ripe peaches, longer for un-ripe peaches. Transfer the peaches to the ice bath and let cool. Remove from ice bath and skins should slip right off. You can also remove the skin with a vegetable peeler. A serrated one works well.
