Help! My Fries!

Oct 1, 2015
Q: I run a small burger and fry business in Nashville TN. We serve about 3200lbs a month of russet potatoes as fries. My produce suppliers have run out of Burbank russets for the year and are only able to supply me with a new-crop of Norkotah russets that are making awful, awful fries that I'm embarrassed to serve! We use a hot-water blanch to cook our 1/2" fries done in a dilute vinegar solution, followed by a 300 degree blanch fry that takes 8-10 minutes to remove most of the moisture. They're then frozen and stored, cooked 2 minutes at 350 degrees for sales. They come out mealy and sweet, not to mention tough, and they last about two minutes before they're basically awful, limp horrors. I've tried lowering the pre-fry temperatures and cooking them longer but I never want to see a Norkotah again... Would switching to a Kennebec or Ranger help until Burbanks come back? Is there some magic trick to cooking these abominations? Complaints are coming in from all directions and I'm in panic mode. Please help!

Unable To Blanch My Fries, What Do I Do?

Nov 21, 2014
Q: I run a small diner and we are looking to use homemade French fries as opposed to the frozen variety. I have seen all of the suggestions about blanching. I have two, two bay Fryolators. I am a 24 hours operation and we have very little time when the fryers are freed up, especially to blanch the volume we need. On an average week, we go through 500lbs of French fries. What other suggestions do you have in order to improve our quality and efficiency?

How to Improve My Frozen Fries

Jul 25, 2014
Q: Can you give me some tips to fix the fry problem at my burger joint? I use the same frozen potato supplier, the same vegetable oil, the same dedicated potato fryer and yet I still get complaints. What’s up with that? Every time I work the line the potatoes seem to be just fine. The customer complaints are in order of issues that come up frequently: fries are too soggy, fries are too dark, fries from one batch are both dark and light, and fries are little bitty pieces.
