01 - Combine water, cinnamon stick, crushed cardamom pods, cloves, ginger slices, 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 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. Strain the tea through a fine mesh strainer into a teapot or heatproof jug, discarding spices and tea leaves. Stir in sweetener to taste. Serve hot, garnished with lemon slices if desired.
