I used skin-on fresh peaches that I cut into 1 to 2-inch chunks. You could use canned peaches instead, but I would recommend buying sliced peaches instead of diced peaches. Here's why. Since I left the peach in rather large chunks instead of dicing it up into small pieces, the ice cream had still had some little chunks of peaches in it. This was the best part! So, if you want to use canned, go for the canned peaches that are in bigger chunks like the slices.
