"Is it ok to put mustard on the burger ?"

What the hell else would you put on a burger?

Horse radish is up to ones own personal preference, of course.

But mayo should never see the toasted side of a hamburger bun.

Mayo on a roast beef sandwich maybe, but never on a burger.

Your mileage may vary and East Texans don't hang 'em as readily as they did in the past. ;^)

Ahem, I would like to speak up for the employment of mayo on hamburgers here in the Great White North.

Sort of like pouring maple syrup on cottage cheese--hard to explain the attraction, but there's no denying the tastiness.

And our beer makes that Texas swill look like...well, swill!

So there! lol ;^)
