I sometimes make a sauce from ketchup, mayo and garlic. If I want to use it as a quick remoulade sauce I add a little horseradish.
Are you still obsessed with Heinz ketchup. Mayochup is a horrible name btw. I remember some of the women making this in bowls at crawfish boils for the kids. Id probably like it on fries.
Isn't it basically Thousand Island dressing without the pickles? It's hardly a new thing. No, I would never buy it. I agree with @tirk, the name is horrible but I'm not sure there's a better combo that still tells the consumer what it is. Chupnaise? No, they are all bad.
I'd never buy it but I do mix it up at a crawfish boil to drag the taters through. Who doesn't like ketchup?
