I'd like some gadget that would just scrub potatoes etc. I did see a hint that those metal dish scrubbers like a Chore Girl were good and have tried one of those. Better than the brush I had flattened the bristles on. My mother used to say all the vitamins were in the peels. Could be depression era or WWII economics. Not much got wasted in our house.I did this for a living many, many years ago.
Diced 300 pounds of potatoes for homefries in a morning way-back as a prep cook (at 16 years old), after the powered peeler took care of that part. Got real quick with it. An hour would do the whole 300#.
I prefer to just wash taters too. I can peel and dice a few pounds pretty quickly still.
Btw a quick way to "home fries" is scrub the dirt off a potato, stab with fork, nuke in microwave, while it is cooking heat skillet with a pat of butter. When it is done slice spud up and toss in skillet, salt and pepper. Add an egg or two in one corner and voila! Breakfast.
