Bit of a bump, but I got re-bit by the DIY Chai Masala bug recently, so I hunted around for recipes. I found this one:

I'd was deliberating over Assam or Darjeling (which I've yet to try, actually), but that post gave me something rather specific: Mamari. I'd not seen that word used before, so I looked about and got a large off Amazon for not a lot of money. Also picked up a Turkish warmer, to make dispensing much easier.
Once the tea and pot come in, I'm liable to gather up the spice mix at the local grocers (0 of which are Indian, sadly) and give it a go.
It's really high on black pepper, so it might need some modification to pass the test with the other half. I'd also like to try it with palm sugar, a la Jay's suggestion, but the first go will be brown or white. Is honey a common sweetener in India?
I'll also experiment with bottling and fridging this for hotter days/always having some on hand. Figuring by next weekend, I should have data.
