I admit, I’m a heretic. I like both. On a bun, one side ketchup, one side mustard (the tangyer the better). On a plate with kraut, more mustard, but I still gotta have a little lovin’ ketchup on the side…awwww yeah baby!
Ketchup is a no-no on a Chicago hot dog. I’m strictly a mustard girl. Mustard, Onion, a slice of pickle. Period. mmmmmm…
Mustard. Boars Head makes some pretty fine mustards, too.
bleaagh
And the last thing I’d murder with it is a good sausage. Mustard (of any kind)–no contest.
Normal hot dogs, like Ballpark franks or something, can have both but it is absolute sacrilege to use ketchup on kielbasas, bratwursts, and other sausages.
Ditto what Aesiron said.
Also, you MUST have brat rolls, NOT hot dog rolls for brats.
Ketchup is for burgers and fries. Mustard for hot dogs, the hotter the better.
ok, so i’m the first heathen to speak up.
a hot dog – excellent vehicle for ketchup, mustard (on opposite sides of the doggy), topped with a lovely sweet pickle relish.
and i looooove ketchup with my kielbasa. gonna have some for dinner tonight, as a matter of fact. yummm.
so, before you pick up stones and start screaming “HERESY”, may i just say i have equal parts Polish and Slovak in my heritage (mixed in with everything else).
so nyah. 
I don’t eat hot dogs. Period.
Bratwurst, on a bun, gets mustard only. (unless kraut is available)
Polish, or smoked sausage, no bun, dipped in… Light Karo syrup.
Mmmmm… the sweet and the spicy all in one.
My husband about tossed his cookies the first time he saw me do this. heh
Catsup is absolutely only for potato products. Not on hamburgers, hot dogs, or pretty much anything else.
Hot dogs - only standard franks - definitely mustard.
Sausages or kielbasa - plain or with BBQ sauce.
Hotdogs? With Ketchup? No thank you.
Very light mustard. and COLESLAW! I think this is a regional thing around my hometown. Everyone else thinks it gross. But I LOVE it. Yummy.
Kethup is only for bad potato products, too. Properly made and seasoned french fries need no ketchup.
Ketchup is only good as a single ingredient for certain sauces, mixed with other condiments on burgers, and as a cover for bland fries.
That’s pretty much it.
One of my benighted roommates, who claims to be pure German, descended from Germans who settled in northern Iowa, eats his bratwurst with ketchup!
I haven’t hit him yet, but I’ll admit to seriously considering it.
As for me, I sort of agree with Neurotik. Ketchup’s only good on fries, hamburgers, and sometimes fried chicken or fish, depending on the mediocrity of said chicken or fish.
Both. And some onions.
This kinda talk just kills me. Put whatever you want ON whatever you want. What’s the worst that could happen? It won’t taste good? The Weiner Police will come and beat you to death?
Get over it, folks, and mind your own business.
Ummm, he sorta asked…
Anyhoo, to quote the immortal words of Detective Harry Callaghan:
“God this stuff isn’t getting to me - the shootings, the knifings, the beatings. Old ladies being bashed in the head for their social security checks. Nah that doesn’t bother me. But you know what does bother me? You know what makes me really sick to my stomach? It’s watching you stuff your face with those hotdogs! Nobody - I mean nobody puts ketchup on a hot dog!”
Mustard is 1st choice. Ketchup if no mustard available.
Both Mustard and Ketchup. Occassionally Relish, but never, EVER onion. After the existance of the Bears, the insistance on no ketchup on hot dogs is the number one reason Chicago sucks.
You should hit him – I’m also descended from Northern Iowa Germans, and the idea of using any tomato product on brats is sacrilegious. Mustard and/or kraut, definitely; grilled/sauteed onions are acceptable, too. That’s it – no other topping should even be mentioned in the brat’s presence.
For me:[ul]
