Every family has its own kadha. Most share a few warm spices and a long simmer.

The spices

Cinnamon, clove, black pepper, dried ginger and tulsi are the usual base. Licorice root adds sweetness.

The simmer

Use a cup and a half of water for every teaspoon of spices and simmer until it reduces to a cup, about ten minutes.

To finish

Strain and add jaggery or honey once it has cooled a little. Drink warm.
