For seasoned home cooks that know their way around a kitchen knife, it can take them anywhere from 60 seconds to peel and slice, and up to 2 minutes for those that work a little slower. To put that into perspective, the average pie takes uses about 4 apples, and 2 quarts of sauce takes about 10. To peel and cut them for your pie, it will take about 8-10 minutes, and for your sauce, it will take you about 12-15 minutes. One of these little gadgets can peel and slice in about 30 seconds. That means you can do all of the prep for your pie in about 2 minutes, and prep time for your sauce will take about 5 minutes.
