I love tapatio. There is a restaurant supply store near work that I go to sometimes and they have all the sizes. It's sort of like a Sam's Club or Costco without the membership and ghetto people.

Niblepin, I think that is the 64 oz size. I get the 32 oz and it looks like this:

It takes me about six weeks to go through it.

p.s. the tapatio doritos are meh...

It's kind of like tabasco but where tobasco has a really strong vinegar taste, tapatio has a really strong crushed red chili flavor. I guess I would say it tastes more "mexican" than tabasco.

It's also thicker and hotter than tabasco, and not so overpowering. I think it would be alright in a bloody mary.
