Glorious ketchup master race.
I can't stand the other two
If you take 2/3 ketchup and 1/3 mayo and mix it, and dip your chicken fingers or fries into it.. Delicious.
Mayo on chips, ketchup with anything else requiring sauce <3
Trees don't flinch.
I like ketchup and mayo equally, though I prefer mayo with sandwiches, and ketchup for fries and hashbrowns. I won't use mustard by itself. In fact, I have never used mustard when making something at home. I've only ever had mustard on a McDonald's cheese burger because it comes with it (and eating McD's is a rarity).
Mustard because out of the 3 it's the only one that can have a large range of flavours and ingredients.
ughhhh, I can't stand mayo on many things. I only have it on basic sandwiches, probably since they've always been on them when I was a kid. I do like that it keeps the sandwich from being dry. And even then, it's the thinest of layers. I can not fathom running my finger along the side of my sandwich, pick up some mayo, and then eat it straight up (gag). That being said, I also have mustard on almost all types of sandwiches, be it yellow, brown or spicy. I do like almost all types of mustard though. Ketchup replaces every other bread-meat combo though: hot dogs, burgers and...well, don't know what else. Of course, mustard is the main attraction.
But there's also BBQ sauce, and that's on a whole different field. I think BBQ sauce might be too spread out though, there's so many types, like this one time, at the Hard Rock Cafe in SF, I had this burger thing, I think it was the south carolina burger or something, but it had the most amazing mustard base BBQ sauce /drool
I use/eat none of them.
But if I'd have to choose, I'd say mustard - it least, mustard tastes good.
I don't really like the taste of ketchup (pure tomato paste is much better), and mayo is just plain disgusting (in addition to containing eggs, which is an exclusion criterion for me anyway).
Definitely ketchup over mayo, even though I do really like mayo. But I don't like mustard all that much.
But really, when it comes down to it, just put tobasco sauce on all the things.
I'm bad, and that's good. I will never be good and that's not bad. There's no one I'd rather be, than me.
A nice stone ground mustard over roast beef YUUUUUM! But they all have a place.
