Asafoetida

Everything about Asafoetida :

this spice is used as a digestive aid, in food as a condiment and in pickles. Its odor is so strong that it must be stored in airtight containers; otherwise the aroma will contaminate other spices stored nearby. However, its odour and flavor become much milder and more pleasant upon heating in oil or ghee, acquiring a taste and aroma reminiscent of sauteed onion and garlic. In India, it is used especially by the merchant caste of the Hindus and by adherents of Jainism and Vaishnavism, who do not eat onions or garlic. It is sed in many vegetarian and lentil dishes to both add flavor and aroma and reduce flatulence.
