Love the Yucateco sauces too, great flavour and heat not like some "chilli" sauces that are just vinegar, red colouring and a ton of capsaicin.
If you guys ever get to Australia you've got to try the output of two of our hot sauce manufacturers. One is Byron Bay chilli which does awesome sauces, my favourite is the mango chilli sauce, nice and sweet with a good zing. The other is the Morrisett chilli factory who have a huge range of hot sauces. They score the heat 10 out of 10, if it says 11 or higher you'll see through time. They've an asian style sweet chilli sauce called Dragons Blood which lives up to its name, I've had a bottle of it in my fridge for almost a decade I use it that sparingly.
Cheers
