Use your paring knife to cut an X on the bottom of each peach
Set a large pot of water to boil. While it is heating up, fill a large mixing bowl with ice and 1 cup of water.
Once your water is boiling, drop in your peaches (3-4 at a time), being careful not to splash boiling water on yourself.
Allow the peaches to rest, submerged, in the boiling water for 40-60 seconds, allowing more time for the peaches that are less ripe.
Immediately transfer the blanched peaches to your ice bath and allow to cool for 1 minute.
Remove the cooled peaches from the ice bath and pat dry with a towel.
Peel skins off from cooled peaches before slicing to use in your favorite recipe.
