Finding a reject coffee grinders for $10, I bought a spare to use as a spice grinder. And then, I came home from New Jersey to discover that the store had some nice trout, but the pantry had no corn meal.
Solution: take a quarter cup of arborio rice. Put it in the coffee mill, grind it for ten or fifteen seconds. Pour the nice, coarse-ground rice flour onto a plate. Add some salt and spices. Dip the trout filets in egg, then dredge in the spiced rice meal, Saute. Better than corn meal!
