Until quite recently, I used the same hot sauce for 30 years.
It's a carrot/habenero sauce made in Belize, which during that time has been sold under two different brand names.
I'm hoping it pops again under a third brand....soon.
I'm a bit lost without it.
Currently, I'm making do with El Yucateco Kutbil-ik. It at least provides some heat if not a great deal of flavor.
