Asafoetida has an extremely strong smell though: if you use the same amount (half teaspoon) as the other spices, it will completely overpower them. It's common in Indian cooking, but the quantity typically used is a literal pinch.
Please don't use pure asafoetida, I don't know of anyone else that does that and it will just smell horrible, along with giving you stomach problems. Even forms of asafoetida you can find in non-western countries are typically mixed with rice flour.

Interesting, because every single report I've heard on it has said the opposite! I don't distrust you, I'm now just wondering what causes the variation!
