We are living in Zurich right now, so whenever I visit SF, I bring a couple of the quart sized bottles of Tapatio with me in my carry on. I wonder what the baggage inspectors think!
We can get Cholula here, and have a Mexican store with lots of variety. And we can buy Tabasco at any market. So I have a whole cupboard full of sauces but Tapatio is the favorite.
We have a new friend from Barbados who is launching his own sauce company. It is also very good and comes in all sorts of temperatures...
