I didn't buy the Cajun Blend (why spend $6 when you may well have all the stuff already?) You can find various versions of the blend online, but at heart you need:
- cayenne pepper
- garlic (can be fresh, as in the recipe)
- black pepper
Basically, you want equal parts of all of them, with perhaps more cayenne pepper for spice, and less allspice (that stuff is strong!!). If you end up making a blend in a bowl and have too much, you can save it in a sealed jar. I just eyeballed it, and added to taste.
Other notes for this recipe: as directed it served 4 people for dinner, and we were fairly hungry. It would not, however, feed 4 hungry athletes. Halved, it would make a good dinner + lunch leftovers portion.
