Tonight I blended this with Russian Caravan black tea from Capital Teas, because when I had the chai alone last night there was no tea flavor to accompany the masala spices. The blend was a HUGE improvement.
I used 1 heaping tablespoon of Rooibos Vanilla Chai and about half to three-quarters of a tablespoon of Russian Caravan. (And like last night, I made it with a bit of rock sugar and half-and-half.) The resulting drink had a much fuller-bodied flavor than the chai produces alone. Very tasty! I will definitely be doing this again (perhaps experimenting with other blends).
