I'm trying to make my own homemade fajitas, for both vegetarian and non vegetarian tasters.
I know they have grocery store pre-mixed fajita seasoning, but I'd like to know how to make my own.
Penzeys (a spice co.) makes theirs from:
salt, black pepper, paprika, Turkish oregano, cayenne pepper, garlic, celery, Mexican oregano, basil, nutmeg, cumin, marjoram, thyme and rosemary.
No numbers are given, and you probably don't need two kinds of oregano, but I've made it before with a similar list, and it is generally insensitive to precise ratios. I'd start with
2x black pepper, paprika, oregano, cayenne, garlic,
1x basil, cumin, marjoram
1/2x nutmeg, thyme, rosemary
bulk up with salt (store-bought stuff is mostly salt), and experiment from there. You can probably find more on google. Add hotter things or anything you find interesting :)
I would guess: salt, pepper, cayenne, cumin, sugar, onion and garlic powder
or you can try this which has a few more items in it: http://busycooks.about.com/od/homemademixes/r/fajitaseasonmix.htm
