Once the kadha has steeped and turned a golden hue, remove it from the heat. Strain the mixture through a fine sieve into a cup, discarding the solids. Add freshly squeezed lemon juice and stir well. For a touch of sweetness, mix in honey while the drink is still warm. Sip this soothing lemon ginger kadha slowly, enjoying its comforting warmth and vibrant, spiced flavor.
