Huh interesting to know (as someone who thinks Five Guys makes the 2nd best fries I've ever had, first being a place local to Denver + Colorado Springs)
Other interesting thing about the five guys which you might already know is that their only proprietary ingredient is the buns. The “seasoned” fry seasoning we threw on there was straight up Kroger brand.
Didn't know that actually. Interesting. I knew the flavoring on the base fries was some sort of peanut oil (which is genius, not to mention delicious).
