You mean the potato? They take whole Russet potatoes and put them through a machine that looks like the old fashioned ringer washers (They buy them from the Navy at salvage). It's filled with a sort of sand, and it scrubs the potatoes. Then they get sliced on an as-needed basis and thrown in the fryer. The potatoes are the size of footballs, by the way. I've never seen anything so big come out of the ground. As home school families, we did a tour. And they fed us.
I don’t want to go too far off topic, but your comment about Home Schooling caught my eye. Is there a school district approved curriculum that home schooling parents go by? I just wonder how you can be sure your child’s grade achievements will be recognized as from an accredited source? I have no kids. God did not chose me (yet) to become a Dad, but I admire parents who are ready and willing to home school their children. Are there ‘get togethers’ with other aged children here and there?
