Dried Lime Tea | Chai Noomi Basra
Take 1 or 2 dried limes, prick them with a fork, and simmer in a litre of water for 15 – 20 minutes, then strain and sweeten to your taste.
The tea can be quite lemon-sour, so sweetening is desirable. Use white sugar or jaggery, or more authentically, Nabat Chuby – Crystallised Sugar on Sticks that are stirred into your tea. You can get these from your Middle Eastern store.
