Grate the ginger using a fine grater or a microplane until you have about 1 teaspoon of grated ginger.

Measure out the cinnamon, cardamom, and black pepper into a small bowl.

In a medium saucepan, bring the cow milk to a simmer over medium heat.

Add the grated ginger, cinnamon, cardamom, and black pepper to the milk and stir well to combine.

Add the loose-leaf black tea to the milk and stir well to combine.

Reduce the heat to low and let the tea simmer for 5-7 minutes, or until the flavors have melded together and the tea has reached your desired strength.

Strain the tea into cups using a fine-mesh sieve or a tea strainer.

Add sugar to taste, if desired, and stir well to combine.
