Meanwhile crack open the cardamom seeds and gather remaining spices. At this point you can either grind them in a pestle and motor or coffee grinder or leave them whole like I do.
Add the spices to the water. Grate the ginger in.
Once the water comes to a boil, add the tea leaves/bags and boil for a minute before adding the sugar.
Pour in the milk and bring the tea to a boil before turning the heat back down to low.
At this stage you can continue to simmer for a little longer or turn the heat off and strain into cups.
Notes
You can add other spices such as star anise, fennel. Adjust spices to your taste. You will come to know your personal preference over time.You can also adjust the milk to water ratio to your preference.You can lightly toast the spices in a pan beforehand to enhance the aroma/flavour.
