I'm so confused. When I saw ketchup on the list I was like, "This isn't a 'What's your favorite way to completely obliterate any flavor the food you're eating has?' poll."
Seriously though. If you put ketchup on something all you taste is ketchup.
I'm not a big condiment guy, myself. I voted mayonnaise but I also like mustard.
For burgers mayo is king. (Though if you have tasty enough onions/tomato/lettuce you don't need anything.)
For sandwiches it just edges out the spicy brown mustard family.
For hot dogs you have to go with neon yellow French's.
Back to ketchup. If you're going to eat the awful stuff at least eat Heinz. Hunts is just sad.
