At the Big River Forge and Ironworks in Lansing, IA, they cut fish from steel plate and use them to make things like this:
When I saw those fish I thought of a different recipe.
Put a steel fish on a cast iron grill and cover it with a piece of cotton cloth.
Sprinkle some salt on it, spray on some water and let the whole thing sit on the picnic table for a few hours on a hot day .
When it is a nice golden color around the edges rinse off the salt and water. Then iron it until it is flat and smooth.
I think it looks yummy, (but then I have strong cravings for fiber.)
