I picked up a sack of Autumn Beauty apples, and went to work. I don't remember how my Mom actually prepared the apples for her famous apple slices. I never peeled apples for her, unlike the thousand pounds of potatoes I've peeled in my lifetime. When they say you are what you eat, I am a potato, no question. Back to the apples. This is what I do. I wash the apples with a drop of dishwashing liquid, and rinse well. I use this apple cutter/corer and drop the apples into cold water that has some lemon juice in it. One lemon to a large pyrex bowl of water. When they are all cut and cored, I peel each slice with a paring knife back into the lemon water. I then drain the apples and place them into a large bowl for mixing.
