Mustard.

If you'll have ketchup or any other toppings...go yellow.  If you,ll just have mustard, use brown or something spicier.

I like ketchup.  I won't apologize for it.  I think it goes well on hotdogs... though not on a Chicago dog.  But that has enough on it to forego the ketchup.  The ketchup would throw off the balance.

But ketchup is sweet and sour and I have a particular like for sweet and sour foods.  So the combination of ketchup, mustard, and very finely diced onions on a good hotdog is fantastic.

Or go another route with a nice bratwurst with sauerkraut and mustard... also excellent.

Chicago dog

what is that?

I guess I'm not a big fan of sweets.  I don't take sugar in my coffee or in my tea, and I rarely have desert.  I like all sorts of tomato sauces, but not ketchup and I know it's the sweet taste that bothers me.  Someone here mentioned sweet mustards.  That sounds awful.  Bananas are good though.  I eat lots of them, as well as mango.  I also have lots of rum drinks when I'm on vacation in the tropics.  We sometimes stay at the all-inclusive resorts which open the bar at about 7AM so I generally start off with rum and pineapple juice for breakfast and continue with rum drinks all day, taking a break from the rum only at lunch and dinner, when I drink beer and wine, respectively, so I guess there are some sweets that I enjoy.  At home I do make my own margaritas as well, usually with 50% tequila, 25% lime juice, and 25% cointreau.  That's another example of sweet and sour that goes down well. 

We have Burman's Spicy Brown mustard in the house at the moment.  I think that's my go-to mustard, mostly because it's really cheap.  Lately, for sandwiches I make a spread of equal parts hummus, brown mustard, and finely-diced garlic.  I put that on bread for sandwich.  On top of that I put sliced jalapeño, then cheese, then roast beef.  On the other side, I put mayonnaise, then cucumber slices, then sliced tomato.  Then I put them together, really fast in one motion so nothing falls out.  Right now I'm using a very dark bread, almost black.  It's pumpernickel, I think.  Around noon I put it in the toaster oven for about five minutes, just enough to lightly crisp the bread and warm the meat and cheese, but not long enough to make the fruits soft. 

I haven't had a hot dog in years, but I have about five sandwiches per week, so we go through lots of mayonnaise and mustard in my house.  There was a hot dog opportunity on Monday around 5, but I needed to get my son to piano practice so I didn't hang around long enough to sample one.  I just grabbed a deviled egg, some Doritos, and a bottle of water.  I did notice that there were three large squeeze bottles of condiments on hand:  French's mustard, Heinz ketchup, and Heinz pickled relish.  I don't know whether that spread represented popular demand, or was simply a reflection of the tastes of the grillmaster.
