01 - Combine water, cinnamon stick, cardamom pods, cloves, ginger, and star anise in a medium saucepan. Bring to a gentle boil over medium heat.
02 - Reduce heat to low and simmer for 5 minutes to allow spices to release their aromatic flavors into the water.
03 - Add loose black tea or tea bags to the simmering spiced water. Continue simmering for 3 minutes, or up to 5 minutes for a stronger brew.
04 - Remove from heat and strain through a fine mesh strainer into a teapot or directly into serving cups. Discard used spices and tea leaves.
05 - Stir in sugar or honey according to taste preference. Serve immediately in heated teacups, garnished with fresh lemon slices if desired.
