With a mortar and pestle, crack 4 pods green cardamom and discard the pods. Grind the cardamom into a fine powder. If you‘re using ginger, cut 1 slice ginger (thin).
Into a small saucepan, pour 2 teacups water.
Add the cardamom powder, 2 tsp sugar, and the ginger slice, and bring it to a boil.
When boiling, add 3 tsp loose black tea.
Simmer for 2–3 minutes.
Add 4–6 Tbsp milk and bring it to boil again.
When boiling again, reduce heat and keep simmering for another 2 minutes.
Remove from heat and strain the tea with a strainer. Serve with a biscuit or cookie.
