I've been using Teeny Tiny Co.'s spices for awhile:
Haven't been disappointed with one yet. Their jerk mix tastes authentic and the Whoopass adds some awesome heat to my breakfast every morning. I've also had their Tandoori Masala and British Curry, both were amazing in coconut milk sauces!
Anybody here know of any solid companies that do similair mixes? I like these ones because they're all fresh course ground and you can see the actual spices, they're not just super fine powders.
