Asafoetida, or asafetida (Ferula assa-foetida) is the dried latex (gum oleoresin) exuded from the living underground rhizome or tap root of several species of Ferula, which is a perennial herb (1 to 1.5 m high). The species is native to the mountains of Afghanistan, and is mainly cultivated in nearby India. As its name suggests, asafoetida has a fetid smell, but in cooked dishes, it delivers a smooth flavor, reminiscent of leeks. It is also known as asant, food of the gods, giant fennel, jowani badian, stinking gum, Devil's dung, hing and ting. This spice is used as a digestive aid, in food as a condiment, and in pickles. It typically works as a flavor enhancer and, used along with turmeric, is a standard component of Indian cuisine, particularly in lentil curries, such as dal, or various 'Pappu' like dosakaya, mamidikaya or tomato pappu, as well as in numerous vegetable dishes. In Indian cuisine, this spice is known as 'hing'.
Please note hing contains wheat flour.
