Asafoetida, Shelf Life : 6 Months

Asafoetida is a plant from the Apiaceae family, which includes carrots, parsley, dill, celery, caraway, fennel, and lovage. Most similar in appearance to fennel, asafoetida smells like rotting feet, which causes many cooks to feel nervous about using the herb. In fact, some countries refer to asafoetida as Devil's Dung because of the foul smell.
