Gather all ingredients including water, milk or plant-based alternative, black tea leaves, fresh ginger, cardamom pods, cinnamon stick, and sweetener.

Bring the water to a boil in a saucepan over medium heat.

Add the sliced ginger, crushed cardamom pods, and cinnamon stick to the boiling water. Let it simmer for 5-7 minutes to infuse the flavors.

Add the black tea leaves and allow the mixture to steep for 3-4 minutes, depending on desired strength.

Pour in the milk or plant-based alternative and bring the chai back to a gentle boil.

Stir in sugar or preferred sweetener, adjusting to taste.

Strain the chai through a fine mesh sieve into cups, garnish if desired, and serve hot.
