Timing the spices

[thebitterguy]

Just a quick question on timing adding spices. I'm making chicken ala king tonight, and I usually add a couple dashes of chipotle powder near the end of the cooking cycle.

Tonight, I added it to the onions, rice and cumin at the beginning, before I added the soup or chicken. Does the timing of spices make a difference? Or what you add it to?

Thanks!
