Soufflé potatoes is an interesting French creation that is made by double-frying potato slices in very hot oil. The potatoes are thinly sliced into uniform slices, then thoroughly dried before being fried. Once fried, the potato slices are removed from the oil and allowed to chill before being fried for a second time in even hotter oil until puffed up, crispy, and golden brown.

The traditional accompanying condiment of choice is sauce béarnaise, which is a combination of butter, egg yolks, lemon, and tarragon. This dish is considered an unforeseen culinary invention from the early 19th century that has been attributed to a certain chef named Collinet.
