That is a great response you received from King Arthur, but still wanted to send you the ingredient that really helped my bread machine results. It took me a while to find the little cook book my friend gave me back in the day when bread machines were a new thing. Try adding vital gluten. It only takes a small amount. This was found in the same area in the store as flour and yeast. I haven't made bread in a long time, so don't really know if it still available. If you are interested, I can send you the name of the book or a recipe.
