Bring the 4 cups of water to a boil in a small saucepan (2-quart).

Remove from heat and add the chai tea bags, steeping for 5 minutes until the water turns deep amber and smells strongly of spice.

Remove the tea bags and stir in the honey and ground cardamom until the honey fully dissolves.

Stir in the fresh lemon juice.

Taste and add more honey if you want it sweeter, one teaspoon at a time.

Divide among 4 heatproof mugs.

Float a lemon wheel on top of each mug and tuck a cinnamon stick in beside it.

Serve hot, within 10 minutes of steeping, while it still sends up steam.
