The Science Behind the French Fry
Ah, French Fries. So delicious, they are the poster child for taking something wholesome and nutritious and making it fattening and artery clogging and they are one of the reasons potatoes get such a bad name. But let’s face it, most of us like a good fry once in a while. I have worked for a potato company for over 15 years and I have seen potatoes fried in a myriad of ways, but did you know there is a wrong and a right way? And that there is a science behind which potatoes are the best for frying?
The key to great fries is in the solids and sugars of the potato. When companies like mine test their potatoes for frying, one of the first things that they look at is the Specific Gravity. This measures the potato for solids. That may sound weird, but potatoes are made up mostly of water. Water and oil don’t mix that well, so the higher the solid or Specific Gravity of a potato, the better chance those French Fries will be golden and delicious. Burbank Russet potatoes have long been hailed as the best frying potatoes and they are still top of the list because their solids are higher than many other potatoes. But a potato that many food service and restaurants are using (which is not available to the general public) is the Pure Gold potato. Unfortunately this potato is ugly with netting all over it and an uneven skin so it is not viable in the consumer market. This potato is a yellow skinned, yellow fleshed potato that yields the best French Fry that I have ever eaten. The fry is always the perfect golden and the taste is unbeatable.
When we fry potatoes we also test for glucose content in the potatoes. It is another important aspect in getting the perfect fry. You don’t want the potato to have too many sugars as it will change the way the potato fries. Remember if you store your potatoes in a refrigerator, the sugar content in that potato goes up and yields fries that aren’t as golden as those stored in a cabinet or pantry.
No matter what type of potato you decide to use for your French Fries, we have a fantastic “how-to” fry video online featuring our Chef Bryan showing how he gets the perfect French Fries. His technique works and produces a golden, delicious French Fry every time. But that isn’t the only way you can fry. Here in our offices we do a fair amount of fry tests so that we can weekly keep our food service customers informed that the potatoes we are shipping that week are frying consistently.
We have a standard way that all of our fry tests are done, that I will share with you here. The first thing we do is we cut the potato into strips. We have a commercial cutter here in our test kitchen that is worth its weight in gold when it comes to cutting fries. It keeps all our fries consistent in size. We then rinse those and spin them in a salad spinner. We spin them to take off the excess water. Once we have the water spun off the fries, we put them into a 300˚ F fryer for 3 ½ minutes. Then we raise them out of the oil and let them sit and “rest” for a couple minutes before returning them to a 350˚F fryer for an additional two minutes. Voila, delicious potatoes.

The salad spinner idea came from our Operation Manager whose department does all the fry testing. It is indeed a great idea to get that water off the fries before they go into the oil!
Those fries look wonderful! I want to try them!
Thanks for all the info to make perfect french fries!
Who doesn’t love a french fry!
I love French fries. 🙂
Never knew that if you stored a potato in the fridge the sugar content goes up…never really thought about the science part of all this….hmmmm
I had no idea about the difference in storing a potato in a pantry! I always keep them in my fridge!! thank you so much for the info!
I love the method of frying french fries!
Before now, I had no idea there was actually a “science” behind french fries, but I do now! I take into deep consideration the fast food places I get my fries from to ensure they are real deal and not infused with any other preservatives and such. This was a very interesting read!
I will definitely use this information next time I want some french fries!
You’ll have to let me know if you find your fries turn out better! We think they do!
You have a lot of good tips on making good french fries.

Thanks! Since my family loves them so much, it’s great to learn the science behind making a pefect French fry! I can’t wait to watch Chef Bryan’s video 🙂
We love french fries in our house. Especially in the summer on the grill.

This is very interesting. Thanks for posting about this.
Fries are my favorites, love this post!
Time to get some.
Very awesome tips on which potatoes to use & how to properly use them for frying. I am a fan of fries, I really do love them (I try not to eat them when I can because I’ll eat them too often), but it’s hard to find any places that actually have good ones. I’ve made some at home before, but never like this.
thanks for the tip!
Cool!
Love the idea of spinning the fries in a salad spinner to dry them!
Oh my goodness! This sounds soooooo yummy!!
These are GREAT tips. Thank you! 🙂
awesome information thank you love french fries though 😉
I want some french fries now!!!
I also would’ve never thought to use a salad spinner to dry the fries .Sounds like you’ve perfected them 🙂
This was interesting to find out what potatoes make the best fries.
Such a time saver to make fries
I always soak my fries in water overnight to pull the starch out
Great information. Who doesn’t love French Fries?
WE make home made deep fried french fries a few times a month here. Its kind of our “treat” for the week if you will. we all love em, as do most.lol. But i have NEVER thought of using the salad spinner to dry them, We found out threw trial and error that they are definitely best dried first. And it can be a little time consuming for somewhat minimal results sometimes. Never again! I can not wait to show off this great idea when we make them next! 😀
WOw i never knew so much research has been put into frying a potatoe. I will look for Burbank Russet potatoes next time im out!!thanks
Wow I learned a lot of new information
Thanks for the tips! We love fries here..potatoes in general! 🙂
Now I have an actual reason for my salad spinner, god knows I dont spin my salad, it just sits up there!

Interesting.
Great blog! Thank you for sharing this great idea! I love French Fry!:)
Ive made my own fries at home. i like to microwave them a bit, too dry them out and then fry.
Now I’m going to have to go and get a commercial cutter never thought of that, but it does make a bunch of sense. Of course the fact that I want French Fries now doesn’t help the matter much…LOL
I love french fries cut into chips.
I have bookmarked this page so I can come back for future reference. I have tried homemade french fries twice before, my kids refused to eat past the first one!
We used to have a fry cutter with 2 different size options but it got packed away and sadly I can’t locate it.
Seems daunting, but I love the science!
Interesting
I would love to try this, fries are my kids favorite
That’s a great tool! I’d love to try it for making fries at home! Thanks!
I’m going to try it!
Definitely going to have to try the salad spinner tip. Can’t believe I never thought of that.
I have never made homemade fries like that.. But I definitely am gonna try these tips… The salad spinner was awesome idea.
Never knew there was a science behind frying potatoes! No wonder mine turn out different every time!
Reblogged this on angiewagg.
That is interesting how the kind of potato most places use is not available to us as a general consumer. I also think the picture of the fry cutter looks cool!
Going to give that a try!
Thanks for all the information to make perfect french fries!
Looks amazing! I need these in my life
I picked up some great pointers! Definitely going to start using my salad spinner more.
Okay, so this has got to be one of the best articles I have come across in a while! Personally, I’m a really big sauce guy and french fries are one of my favorite things (as much as my arteries may hate me when I’m older). It’s hard for me to pass on a good fry, but I’m not sure if I have ever had a pure gold potato fry before. Thanks for the thorough education in the science of french fries!
