It costs 6 euros and you could gain weight, but if you’re ever in the medieval city of Bruges, Belgium, check out the new “Friet Museum.” Here is everything you ever wanted to know about potatoes, and more than you ever thought of asking, and it’s amusing as well as interesting.

You’ll learn, for example, that “French Fries” really aren’t. They should be called “Belgian Fries.” But when some soldiers in World War I came upon some Belgians cooking up potatoes in a kettle of boiling oil, the Belgians were speaking French, so the soldiers dubbed the delicious fried spuds “French Fries.”

The tour takes you down through the history of potatoes beginning some 10,000 years ago in the mountains of South America. The root vegetable was introduced to Europe by Spanish conquistadores in the late 1500s. There are various displays on how many different kinds of potatoes there are, where they are cultivated, and how the best chefs prepare their fried potatoes.

You learn that the very first Belgian Fries were cooked up one cold winter day during the 1700s when the supply of small fish ran low and enterprising cooks cut potatoes into fish shapes and fried them for their customers. It would be fun to know how many millions (or billions) of potatoes end up in little fried strips in modern times.

Artifacts range from primitive deep-fat fryers and Inca vases shaped like potatoes to an early-20th-Century kitchen and Art Deco posters featuring the humble spud.

At the end of the tour, you can head down to the the museum cafe in the basement, where master chefs fry up heaping helpings of Belgian Fries and you can salt them to taste and munch to your heart’s content. You can even put mayonnaise on them instead of ketchup, if you’re so inclined.

The Friet Museum is housed in the Saaihalle, one of Bruges’ oldest buildings. The originator of the Friet Museum is Eddy Van Belle who also has a lamp museum, Lumina Domestica, and a chocolate museum, Choco Story, in Bruges.
