Asafoetida

Asafoetida is a sulphurous, onion-smelling spice used in Indian cooking. The sulphur smell dissipates in cooking and just leaves a "onion" like flavor. Particularly useful in vegetarian cooking. Asafoetida comes from the sap of a plant similar to a giant fennel. The sap dries into a hard resin and it is sold in "lump" and ground form. Use in small amounts with dried beans and vegetables. Buy asafoetida in any Indian grocery store or online at Amazon.  Asafoetida Powder
