Bacon grease is an excellent flavor carrier, infusing the batter with an unmatched depth and smokiness, and creating crisp, crunchy crust. Bacon grease can also be used to coat a cast iron skillet with cornbread, preventing it from sticking to it, and enhancing the dish's overall flavor. This is backed by science, which suggests aromatic and flavor compounds bind to fat molecules, which are then released during chewing. This can enhance texture and flavor perception, while adding a rich, savory umami note to any dish, including cornbread. The bacon grease is also used as a more flavorful substitute for olive oil and other cooking fats, particularly for roasting vegetables like broccoli, carrots, or green beans.
