In a small saucepan, combine 1 cup (240 ml) water, cinnamon sticks, crushed cardamom pods, cloves, peppercorns, and sliced ginger. Bring to a gentle boil over medium heat.

Lower the heat and simmer the spices for 8-10 minutes. If it reduces too much, add a splash of water.

Add the black tea leaves or tea bags and steep for 3-5 minutes. For a bold flavor, steep for about 4 minutes.

Strain the mixture through a fine mesh strainer into a clean saucepan or serving pot, discarding the spices and tea leaves.

Add 1 cup (240 ml) of your choice of milk to the strained chai. Warm over low heat, stirring gently. Avoid boiling.

Stir in 2 tablespoons of sweetener and ½ teaspoon of vanilla extract if using. Adjust sweetness as needed.

Optional: Froth the chai tea latte using a handheld frother or shake it vigorously in a sealed jar for 20 seconds.

Serve immediately in your favorite mug, optionally sprinkled with cinnamon or nutmeg.
