Taco Seasoning

I didn't have any taco seasoning packets in the cupboard the other day, so I decided to make up my own seasoning. I used this recipe, a hodgepodge of different recipes I found here and there:
1 T. chili powder
1/4 tsp. garlic powder
1/4 tsp. onion powder
1/4 tsp. red pepper flakes (I didn't have these, and used just a bit of cayenne pepper instead)
1/4 tsp. oregano
1/2 tsp. paprika
1 1/2 tsp. cumin (I was out of cumin, so I omitted this time)
1 tsp. sea salt
1 tsp. black pepper
1 1/2 tsp. flour or cornstarch (I used flour this time)
For tacos, use 2 T. to 1/4 cup water with the mixture.
