I hope this is helpful and not just a solution for my problem.
I love the good old Northern Spy apple for fresh eating, preserving, sauce, pie and cake.
They are huge — way too big for the typical peeler-corer-slicer, or the wedge-corer above. So I used that to mark the slices for consistent size, and was able to whack them up fast, and paring the 1/3” slices was easy.
I made an Italian apple cake that is loaded with apples which are held in place by a bit of moist eggy cake.
