+1, a wooden spoon is by far the best way to simplify the cutting of the potatoes.

Being of Swedish descent, I ate these potatoes often while growing up, but I have to admit that until today I had no idea what they were officially called. We just called them "Swedish potatoes" and my mom used her grandma's recipe (which just called for breadcrumbs, parmesan cheese, salt, pepper and butter as a topping, delicious!).
