For your spice rack: Cajun Spice Mix
The Red Lobster biscuits copycat recipe called for Cajun seasoning, and after browsing around there seems to be several different variations of it. I finally settled with the recipe from Allrecipes.com, since I had all the required ingredients on hand.
2 teaspoons salt
2 teaspoons garlic powder
2 1/2 teaspoons paprika
1 teaspoon ground black pepper
1 teaspoon onion powder
1 teaspoon cayenne pepper
1 1/4 teaspoons dried oregano
1 1/4 teaspoons dried thyme
1/2 teaspoon red pepper flakes (optional)
Put all the ingredients into an airtight container. Close the lid and shake well to mix.
