Man, is Michel (aka King Cone) obsessed with French Belgian Fries! Here's a Belgian website dedicated to the fried potato. The site includes a section dedicated to the "frietkot" or fry shack, little booths that serve only fries.
He also includes the recipe for preparing and cooking a proper fry, which I endorse. The twice cooked method is the ultimate way of insuring a crispy fry that's tender inside. Unfortunately there's no direct link to the recipes section so follow the main link above and click on 'recipes' in the left sidebar.
BTW, a Belgian fry is never served with ketchup or vinegar, only mayonaise. Okay, he kinda loses me there...
Check out the site, this guy is really into it!
My brother inlaw does the mayo and fries, I don't get it either.
I'm a fan of the double deep fry action as well, but since the fries have to be washed, then dried semi-individually, I don't do it much anymore.
