Getting flavor to stick in milk tea
Have you tried steeping the tea in the milk? Whenever I make milk tea, I always do a 3/5th cup of whole milk, 1/5th cup of condensed milk (for sweetness) and 1/5th cup of water. I then bring the mixture of milks and water up to about 140F and steep my green tea and spices in it. This gives me a nice thick latte-like consistency and strong milk taste without overwhelming the tea and chai spices.
