With this, I can get a pile of apples ready for a pie or a crisp in a real hurry. I'm sure every one of you have already seen one, and many of you probably have one.
Below: When the apple has gone 'all the way through', like this, I carefully pull it off and chop it up as seen in the bottom photo.
Below: If I want slices for an apple pie, I cut the slices in half or thirds. For a recipe that calls for chopped apples, I make 1/2" cuts all the way around. This works so SLICK. SLICK and QUICK!!!!!
