Asafoetida is a plant that has a bad smell and tastes bitter. It is sometimes called "devil's dung." People use asafoetida resin, a gum-like material, as medicine. Asafoetida resin is produced by solidifying juice that comes out of cuts made in the plant's living roots.
Asafoetida is best used as a background note for other complimentary spices, like cumin, mustard seeds, dried chiles, curry leaves, ginger, and garlic. Add any combination of these things to your tarka to drizzle over beans, stewed vegetables, or anything at all. Or start your dish with asafoetida.
