I think it is the tamarind paste that throws off the flavor a lot in the Old Bay branded Bloody Mary mix (besides maybe a pinch too much of Old Bay, which I know is unheard of, especially with the need for rimmers of it on Bloody Marys)... Gives it almost like a BBQ aftertaste for some reason, and not in a good way... And I'm a fan of tamarind so don't know what's up with it. Definitely needs fresh lemon and lime, and to be diluted with a bit more something...
