This might have already been said. Try your formula with a better sugar or flour. During the baking process most of the impurities rise to the top. The skin is sweeter and some people really like this. For me, I can do without the roach parts and such.
I've been following along for a while. Sounds like you're getting close. The one suggestion I have is to rid yourself

I installed a couple of kuisinarte wall ovens two years ago, I really like them with the enclosed elements. I put a small gas on the otherside. I have had no problem with recovery. I did install a Vent a hood brand which helps. made right here in Tx. for about a .25 of the price. Warming lights. I have to tell you my 6 burner Vulcan has given a lot of problems,
