Gather your ingredients: red chili powder, guajillo chile powder, smoked paprika, pink salt, and dehydrated lime juice powder, measuring them accurately in a small mixing bowl.

Combine the red chili powder and guajillo chile powder in your mixing bowl as the base of your Tajin seasoning, then add smoked paprika and pink salt mixed evenly.

Sprinkle in the dehydrated lime juice powder and mix thoroughly using a whisk or fork until all ingredients are combined into a uniform texture.

Store the completed spice blend in an airtight jar and label it with the date, keeping it in a cool, dark place to maintain its flavor.

Enjoy your homemade Tajin seasoning by sprinkling it over fruits like mango or watermelon and using it to enhance grilled meats and roasted vegetables.
