Pull out all the chosen spices and line them up for easy access. Take a quick sniff test - if any smell faded or stale, it's best to replace them with fresh ones.

Measure out the desired amount of each spice based on your preferences and add them to a mixing bowl. A good starting point would be 1 Tbsp chili powder, 1 tsp cumin, 1/2 tsp garlic powder, etc.

Stir, whisk or shake everything together until fully incorporated. Break up any clumps and evenly distribute.

Once combined, transfer your custom spice mix to an airtight container such as a mason jar or reusable shaker. Clearly label for easy identification.

And just like that, you've crafted your very own signature taco powder to use anytime tacos are on the menu!
