No, it’s not flour that’s been weathered and tested. Seasoned flour is simply regular flour with seasonings added. You’ve likely seen it as an ingredient in recipes where foods are first oated in flour, then fried or sauteed. The seasonings are incorporated to add extra flavor to the food.
In its base form, salt and pepper are all you need to make seasoned flour. Some recipes will suggest other flavors to add, but it’s easy to create your own spice blend to take your seasoned flour to your spice rack’s next level.
Think about the herbs or spices present in your dish and use flavors you think will complement them. If adding spices on the fly seems out of your league, play it safe with big pinches of salt and pepper.
Whatever seasonings you choose, add enough so that you’ll actually be able to taste it when your dish is done.
