It is impossible to make a proper Bloody Mary without Tabasco Sauce!
You are probably right there. I was trying to think of a situation where I would prefer Tabasco over some other hot sauce and I think that would be the place.
I have been making my own hot sauces lately, and I think I would prefer them over Tabasco for most purposes for their complexity. Before I started doing my own, I was getting into a whole bunch of different special versions, not necessarily artisanal and not necessarily all that potent, along with Cholula, which I think I would use as my general hot sauce. Frank's for wings certainly. I think I would reach for Crystal or Texas Pete over Tabasco for things other than Bloody Marys.
Nothing wrong with Tabasco and I guess I admit to not keeping up with the newer flavors apart from the original version. But it does seem simpler than my real favorites.
