In a saucepan, bring water to a boil.
Add black tea leaves, grated ginger, crushed cardamom pods, cinnamon stick, and cloves to the boiling water.
Let it simmer for 5 minutes on low heat.
Add milk and sugar to the saucepan and let it simmer for another 5 minutes.
Remove from heat and strain the tea into individual cups.
Heat a piece of charcoal until red hot.
Place the red-hot charcoal in a small steel bowl and put the bowl in the middle of the tea-filled cups.
Drizzle a few drops of ghee or oil on the charcoal.
Cover the cups immediately to trap the smoke.
Let it sit for about 2-3 minutes to infuse the tea with the smoky flavor.
Uncover the cups and discard the charcoal bowl.
Serve the Tandoori Chai hot and enjoy!
