2. Ingredients Matter
The spices you choose play a significant role in the final taste of the taco mix. For instance, swapping smoked paprika for regular paprika can change the entire flavor of the spice. Experiment with different combinations until you find a spice mix you think works for your taste.
Wherever possible, always shop for your spices at a spice merchant. While spices do last a long time when stored correctly, they are at risk of damage during transportation from the spice manufacturer to the store. If the spice suffers exposure to high levels of heat during transport, it might affect the final taste and constituency.
We recommend that you search for a spice dealer in your area. If you manage to find one local to you, the dealer can mix your taco spice at their shop under your directions. All you need to do is return home and place the spices in storage in the fridge to keep them fresh and full of flavor.
