Asafoetida is a hard resinous gum, grayish-white when fresh, darkening with age to yellow, red and eventually brown. It is sold in blocks or pieces as a gum and more frequently as a fine yellow powder, sometimes crystalline or granulated.
Bouquet: a pungent smell of rotting onions or sulfur. The smell dissipates with cooking.
Flavour: on its own, extremely unpleasant, like concentrated rotten garlic. When cooked, it adds an onion-like flavour.
