01 - Combine water, cinnamon stick, crushed cardamom pods, cloves, ginger slices, and star anise if using in a medium saucepan. Bring to a gentle boil over medium heat.
02 - Reduce heat to low and simmer for 5 minutes to allow the spices to fully infuse the water with their aromatic flavors.
03 - Add loose black tea or tea bags to the spiced water. Simmer for 3 minutes, or up to 5 minutes for a stronger brew.
04 - Remove from heat and strain the tea through a fine mesh strainer into a teapot or heatproof jug. Discard the spent spices and tea leaves or bags.
05 - Stir in sugar or honey to taste. Pour into teacups and garnish with lemon slices if desired. Serve hot.
