doomed to eat Heinz
There's worse things, like going to a nice restaurant for brunch and finding they offer some organic ketchup (occasionally even Hunts) or worse... make their own. Sir Kensingtons is okay, but not great.Some people just want to dispute the fact that Heinz is, empirically, a great product. In my opinion, Heinz might even be a special case of this. What I mean by this is I'm not sure I've ever used Heinz somewhere where I thought "you know, Sir Kensingtons would really be better in this situation".
French's mustard is good, but not as versatile. I'd easily prefer a sandwich with Beaver over French's in most cases, but French's over any dijon for a hot dog. For mayo, Hellmans is closer to the class Heinz is in, but I'm happy with Kewpie in many cases over Hellmans, and a home-made aioli/mayo can bring something extra to certain dishes. That being said, I'd rather take Kewpie over Kraft Mayo and always over miracle whip.
Peanut butter is a little trickier. The major brands are all very good - Skippy, Jif. Off brands can be good. I don't mind old fashioned peanut butter, but it can't compare to the creaminess/texture of the big guys. It's also a pain in the ass to stir it and putting it in the fridge as a hack for that is a terrible workaround.
