I mix mayo and ketchup for my fries.
Hellman’s doesn’t exist west of the Rockies. Yes, some people do put mayonnaise on their chips. Yes there are better mayonnaise out there. Duke’s Double Yolk mayo comes to mind. Good if you don’t want to live past 40. And to me, Kraft’s Mayonnaise with Olive oil with your own added dry mustard is the best ‘light’ mayonnaise out there.
