This is a harder question than I thought it would be. First I thought: Definitely Ketchup. But then I started thinking about the taste of mustard. If you compare the two, it's really hard to tell which is better, since they have much different tastes. I really depends on how I feel at the time. But you can have more stuff with ketchup than mustard. So.... I'll have to go with ketchup.
in kindergarten one time for lunch we had hotdogs and we thought mixing ketchup and mustard together was gross so I did on my hotdog and guess what? ...... It tasted great! lol so I like both
Depends on the type of mustard. If it's Dijon ketchup wins. If it's plain ol' regular mustard it's a tie. It's not that I can't handle the spiciness, it's just that the spicy doesn't go well with the mustard's flavor.
Me too, you can put it on more things than mustard and it'll taste well. I just had a egg sandwich for breakfast and I put ketchup on it. If I would've put mustard on it, then I don't think it would taste good.
