For this Gluten Free Peach Crisp recipe, you can remove the skin or leave it on—whatever you prefer. If you’d like to remove the skin, I recently saw this trick from Tastes Better From Scratch: Place 2-3 peaches into a pot of boiling water. Leave them in the water for about 30 seconds, and then transfer to an ice-water bath. The ice water bath will shock them and keep the peach flesh from cooking, but the peach skin will be so easy to peel that you won't even need a knife!
