Make your own Taco Seasoning (from Creative Homemaking)

6 teaspoons chili powder
5 teaspoons paprika
4 1/2 teaspoons cumin
2 1/2 teaspoons garlic powder
3 teaspoons onion powder
1/4 teaspoon cayenne pepper

Combine all ingredients together, and mix well. This should be
stored in an airtight container for up to six months.

You can vary this recipe by adding some oregano to the mix. One of the best
things about making your own spice blend is that you get to
change and modify the recipe for your personal tastes. If you
like spicy food, you can add more cayenne pepper. If you don't
like it so spicy, you can leave the cayenne pepper out of the
recipe.

To use this seasoning mix, simply use 3 tablespoons and a cup of
water once you have browned one pound of ground beef. Simply add
the seasoning mix, and water, and allow the water to reduce by
1/2 and you have some tacos that have been seasoned perfectly,
and you did it all yourself without having to buy a commercial
mix.
