As it turns out, you need to fry a French fry at a 0 degree inclination (i.e. flat) under 3 Gs for an optimally crispy French fry crust. The gas giant Jupiter has a "surface" gravity of nearly 3 times Earth gravity and therefore has the ideal gravitational conditions for cooking French fries!

It's not all good frying news, however. The bottoms of the centrifuged fries became soggy as water vapor rushed out of the potato, insulating that part of the potato against frying. So, even though 3G fries have a lovely crunchy crust, they are half-soggy. (Pro tip: Perhaps they need a flip half-way through the cooking cycle?)
Although this research may sound rather fanciful, its intent is to reveal the cooking characteristics of foodstuffs in different gravitational environments for future space travelers. But, until we see drive-thrus on Jupiter,* probably the only optimized French frying problem we need to worry about is when you last changed that gloopy brown sludge sitting at the bottom of your deep fat fryer.
