Bread – Cast Iron Bread Tin is Leaving Black Spots on Bread

bread

Im using cast iron baking tins for my bread recipe (just standard whole wheat flour, yeast, salt).

I notice that after baking the bread it will have black spots on the bottom and sides. If I bake the bread further they only get worse.

What is this? It looks like mold, but I highly doubt that is what it is. I clean the tins after each use and keep them seasoned and oiled. Anyone else have this problem?enter image description hereenter image description here

I think this is just iron reacting with the bread. In cast iron, I think your choices are to either:

  • line the pan with baking paper (then it's hardly bread anymore ):
  • heat up the pan to oven temperature first, and then drop in the dough, returning the pan to the oven. This technique is often used with cornbread.
