Instructions:

1. Start by preparing the dried red chili peppers. Remove the stems and seeds to reduce the heat level if desired. Wear gloves and be cautious, as chili peppers can be very spicy.
2. Heat a dry skillet or pan over medium heat. Toast the dried red chili peppers, cumin seeds, and dried oregano for a few minutes until they become fragrant. Stir frequently to avoid burning.
3. Remove the toasted ingredients from the heat and allow them to cool to room temperature.
4. Once cooled, transfer the toasted chili peppers, cumin seeds, and dried oregano to a spice grinder or blender.
5. Add the paprika, garlic powder, onion powder, cayenne pepper, and salt (if using) to the grinder or blender.
6. Grind all the ingredients together until you have a uniform and fine chili powder blend.
7. Taste the chili powder and adjust the salt or cayenne pepper according to your preference.
8. Store the homemade chili powder in an airtight container in a cool, dry place. It should remain flavorful for several months.

To Use Chili Powder:

1. Chili powder is commonly used in chili con carne, taco seasoning, and enchilada sauce for Tex-Mex and Mexican dishes.
2. It can also be used to season roasted or grilled meats, vegetables, and even popcorn for a spicy kick.
3. Adjust the quantity of chili powder in your recipes to control the level of spiciness and flavor.

Keep in mind that chili powders can vary in heat level and flavor depending on the type of chili peppers used. Homemade chili powder allows you to customize the blend to your liking.
