My favorite, so much that I went nuts one week with some I had ordered and broken it down by weight as best can be separated and determined, with some basic rounding. This formula will provide a little over 5 ounces of total Masala Chai, or just under 4 ounces of the Masala Spice Mixture alone.
Masala spices
5 grams of whole Cardamom
45 grams of Cardamom seed
20 grams Ginger, chipped
20 grams Cinnamon, chipped
8 grams Cloves, whole
5 grams Star anise, broken
5 grams Black pepper
2 grams Fennel
TEA (27% total weight)
15 grams Rooibos
25 grams Black Assam
Amounts for one cup
2 tsp of Black Assam + 1 tsp Rooibos = ~ 6 grams
2.3 tsp of whole/chipped spice Masala
Excellent served with sweetened condensed milk or with milk powder and sugar.
Not sure it can be very authentic with Rooibos in it, though.
