My personal homemade taco seasoning includes:
1 Tbs. chili powder (preferably hot!)
1 tsp. Ground Cumin, Garlic Powder, Paprika, Oregano, Sugar
1/2 tsp. Salt
I use a couple spoonfuls per 1 pound of ground beef or chicken for tacos. This tastes WAY better than ANY taco seasoning at the store. You may find you like to personalize yours to taste (more of this, less of that, etc.). Enjoy!
