Basically, these burgers are gumbo you can eat without a spoon. The flavors here are discernible and assertive. The “ketchup” has that toasty roux and tomato paste that brings it all together. Take your roux right to the edge of burnt to get maximum toasty flavor, but don’t burn it or it’ll be ruined. Milk chocolate is a good indicator, but if you’re risk averse, stop at café au lait. This would be great with cornbread soup that you could dip the burgers into.
