There is a sea of cornflake breadcrumbs recipes you can try, and all revolve around the same methods and are very, very easy to make. This particular cornflake breadcrumb recipe is my personal favorite because it contains seasoning, and the breadcrumbs you will get as a result are seasoning in themselves.
Depending on how finely you want to crush the cornflakes, you will also need a rolling pin or a food processor. This recipe calls for the rolling pin method, but feel free to experiment.
Place the cornflakes into a zip lock bag and roll the bag over with the rolling pin until you are satisfied with the size of the ground cornflakes.
Remove the rolled cornflakes from the bag and place them in a large mixing bowl.
Add the spices into the bowl and mix everything together.
Transfer the mixture into an airtight container and store it in a dry and dark area.
