Rinse the fenugreek seeds under cool running water to remove any dust or debris.
Add the water, fenugreek seeds, cinnamon stick, and cardamom pod (if using) to a small saucepan.
Bring the mixture to a gentle boil, then immediately reduce the heat to a low simmer.
Simmer for 8 to 10 minutes until the tea turns a light golden color and develops a warm herbal aroma.
Remove from the heat and strain the tea through a fine-mesh strainer into serving mugs.
Stir in honey or maple syrup if desired, then add a squeeze of fresh lemon for a brighter flavor. Serve warm or let cool and pour over ice.
