I've wondered about finding a way to try them. Know a guy who unwittingly destroyed his home by overcooking them.
Personally, I don't like anything on my fries - it makes me wince when waitstaff or someone at a fast food place runs down the list of sauces they have for them AFTER I've said no thanks. Hot, and salted. A little greasy. Maybe Old Bay - garlic - seasoned salt - but no liquids.
Unless they're bad - then ketchup.
