I’m not sure if mixing a decaf and regular black tea is taboo but I did it. My boy needed a quick cup of tea for work with a little kick. I only had a wee bit of the lovely Paris from Harney & Sons left so I quickly mixed in some Vanilla Comoro. I’m really diggin’ the result! I used 1 tsp Paris, 2 tsp Vanilla Comoro to make 24 ounces. I’m going to try equal parts when I order more Paris.
