I have seasoned the bread pan, and generously apply oil before putting the dough in (note: I use no-knead method and let my bread rise in the pan, then put it straight into oven). The bread itself turns out great, and white bread does not stick. However my whole wheat honey bread sticks no matter what I do. I suspect this is due to sugar in the honey, but am not sure. Is there anything else I can do to prevent sticking?
If you are having trouble with honey-wheat bread sticking in your cast iron pan, there are several things worth trying:
Make sure the pan is well seasoned. There should be a smooth, continuously black surface over the entire food contact area of the pan.
Spray the pan with oil before adding the bread. This may or may not work but is probably worth a try.
Do not add the loaf directly to the cast iron pan. Put it in on a parchment sheet, so that it is not in direct contact with the oven. You will have to peel off the parchment afterwards, but it should reduce sticking.
In fact, in some versions of no-knead bread, this is the recommended method until the loaf is well set, then you remove the parchment for the latter part of the baking to facilitate bottom crust development.
Honey-wheat breads are going to be inherently more sticky than a pure white bread, especially because of the sugar, and because the whole wheat bran in the loaf tends to cut the gluten strands, making it hard to get a tightly stretched gluten network on the outside of your loaf, which is one of the things that makes it less likely to stick.
Another thought would be to try removing the dough from the pan, preheating the pan, and then tossing the dough back in. Adding food to a hot pan will reduce sticking, as will ensuring the food you're adding to the hot pan isn't cold.
It may sound a little weird, but it's pretty standard to get cast iron nice and hot before adding food, for that purpose. Haven't tried it with bread, but it'd be worth a shot.
coat the pan with butter or crisco and heat up to temp first, then let your food get to room temp before adding to pan. should eliminate sticking problems. flax seed oil has been known to flake off in food, it also has a lower smoke point and will not hold up well in seasoning over time with cast iron, use pure lard or crisco and you will have much better results
