1. In a small saucepan, bring 1 cup of water to a boil.
2. Add the mustard seeds and fenugreek seeds; let them simmer for about 2 minutes to infuse the flavors.

5. While the tea is still warm, add the jaggery (or honey) and stir until dissolved.
6. Allow the tea to cool to room temperature, then refrigerate until chilled.
7. Once chilled, stir in the lemon juice.
8. Serve over ice cubes and garnish with fresh mint leaves.
