Pour 2 cups milk in a medium pot set over medium-high heat. Add the molasses, a pinch of salt, cardamom, star anise, cloves, ginger and cinnamon.
Bring to a boil and reduce heat to low. Simmer for 8 minutes. Stir, add the tea leaves and allow to steep with spices, stirring frequently to keep milk from boiling over, about 1 minute. Remove from heat and stir in the remaining milk.
Place a fine-mesh sieve over a teapot or serving container. Pour in the liquid, and discard the leaves and spices. Divide among 4 cups and serve immediately.
