Kadha (spiced herbal decoction)
When the fog settles over Delhi, Lucknow and the plains of Uttar Pradesh in December, or whenever the monsoon brings coughs round the house, someone puts a pan of kadha on the stove. Tulsi leaves, ginger, black pepper, cinnamon, cloves and sometimes a little ajwain are boiled hard until the water reduces by half, then sweetened with jaggery and sipped in small cups, morning or night. It is not a gentle tea: it is hot, peppery, clove-numbing and earthy, with a dark amber colour and a sweet edge. It is traditionally drunk for coughs and colds; it does not replace medical care, and anyone who is pregnant, on medication or giving it to small children should keep it mild and check with a doctor. The common mistake is simmering it gently like tea: kadha needs a steady boil so the spices give up their strength and the liquid reduces. It is ready when the volume has halved and the brew is deep amber and pungent. Chef's tip: crush the pepper and cloves just before they go in; whole spices hardly flavour the water in this short time.
