I’m right there with you. Typically I will use less ketchup than mustard, but I have always liked both on hot dogs. Relish sometimes as well.
If we talk Bratwurst, that’s a different game, then it depends on the brat.
I must say I do not relish relish. :-)
Brats are definitely a different game.
But you are sure to be flamed for agreeing on the tomato based condiment... ;-) Or would that be grilled?
