Mu‘assel ( which means "honeyed"), or shisha, is a syrupy tobacco mix containing molasses and vegetable glycerol which is smoked in a hookah.
Shisha , from the Persian word shīshe , meaning glass, is the common term for the hookah itself in Egypt, Sudan, and the Arab countries of the Persian Gulf (including Kuwait, Bahrain, Qatar, Oman, UAE, and Saudi Arabia), and in Algeria, Morocco, Tunisia, Somalia and Yemen. Initial traces of hookah smoking have been found in the North Western provinces of India in the states of Rajasthan and Gujarat.
Typical flavors of mu‘assel include apple which has a strong aniseed flavour, grape, guava, lemon, mint, as well as many other fruit based mixes. Unusual flavors, including white gummy bear, blueberry muffin, spiced chai and Powerbull flavor (similar to the flavor of a Red Bull energy drink), have been introduced in recent years by modern tobacco manufacturers.
