Enter Cook's Thesaurus, a great site that serves an important purpose: finding substitute ingredients when you are missing that certain, special, essential ingredient. In this case, I was missing asefetida, a spice that falls somewhere around an onion and garlic mixture. It turns out that I can use onion powder and/or garlic powder as a substitute - recipe saved!

(Note: I'm working on fixing the links along the sidebar, as we have lots of good sites that deserve a link - like Cook's Thesaurus. This will be fixed shortly.)
