Combine Spices: Mix the ingredients together in a bowl. Transfer to an airtight container or jar and store in a cool, dry, place for up to 6 months.
Once you’ve made your Tex Mex seasoning, feel free to make adjustments and add more, less, or remove some of the ingredients depending on your preference.
I prefer to store my spice blends in jars, as the screw-top lid keeps them most fresh.
If you’re using a freshly washed container, make sure it’s 100% dry before pouring in the seasoning. I’ll dry my jar with a kitchen towel, then let is sit upside down on a drying rack for 20-30 minutes to be extra sure. If there is moisture present in the container, you risk having the spice mixture spoiled.
Mark the date on the jar that you mixed up your blend to keep better track of its age! You can give it the good ol' sniff test before using once it gets older to see if it's still usable.
When properly stored, Tex Mex seasoning will stay fresh for 6 months. Since it’s completely dry, it will never go “bad” or rotten, it’ll simply go a bit stale and lose its potency.
