Chai tea Concentrate

I love chai, but it's really a pain to make from scratch. I'm also a snob and don't like most of the mixes available at the store. They're either too sweet or not spicy enough or whatever. Today I was reading Angry Chicken and came across this recipe for a mix that's kept in the fridge for 6 months. It is perfect! No too sweet and with the addition of 1/4 tsp ground pepper is definitely spicy enough! Enjoy!
