Kismet. She's a fickle mistress.
Having sworn allegiance to Tabasco - Chipotle smoky BBQ pepper sauce 60ML
I then discover the taste sensation that is Cholula Chipotle Hot Sauce. That's not to decry the virtues of the Tabasco. Oh no, for I, being a geek, conducted a taste test, and here dear readers are my results.
The Tabasco is hotter than that Cholula, and while that's entirely down to personal preference, the slightly reduced heat of the Cholula allows you to apply it more liberally. No bad thing!
I found the Tabasco to be a slightly sharper, almost vinegary taste whereas the Cholula (as fellow Amazonians have rightly noted) has a more mellow, almost woody taste to it. Again, personal preference applies.
In short, they're different beasts. I'll carry on using both as they're both great in different ways, but I'll probably use the Tabasco as an ingredient (it's excellent in Chilli Con Carne), but use the Chipotle on its own as a sauce. It's tasty stuff!
