What most impresses me is how much can be left in the bottle when it's "empty" getting that last half out is hard to impossible. Lots of engineering must have gone into that. If it were not so cheap it would bother me even more.
My significant other puts ketchup on her hot dogs; this just doesn’t seem right to me, but I try not to judge. As for me, I long ago went down the path of spicy brown mustards, and have never turned back. Going even harder core, I now favor mustards with horseradish. A soft pretzel with lots of spicy brown mustard on it is among my favorite indulgences!
I have a collection of mustards. My son said, no Mom, don't bring those to Massachusetts. So he will buy me more, no matter what the cost (I bargained with him).
Several years ago, we visited the last operating mustard mill in Maine. At one time, there had been seven mustard mills in that small town, mostly supplying the Canadian sardine industry.
