The brand name "Pringles" is a baked potato paste. I wonder if we can buy a "waffle iron" or press designed to make chips?
It would be a labor intensive process, even if your press could make multiple chips at a time.
Perhaps they could be made like pancakes, using about 1/2 tablespoon of soupy potato paste at a time? I've made "dollar" pancakes like this, so potatoes should work about the same. Except you don't need the baking soda/cream of tartar to make them rise.
