I made this over the weekend with the grain from last weekend's Best Bitter brew - MO with a little corn and crystal 40. It worked really well, but gave a very sticky dough, although I made two modifications. A little more flour/less water at the start should fix that.
Firstly, I used a molasses in place of the sugar - this gives a good color to the bread and crust and supports the malt flavor well.
Secondly, I used the hearth bread baking method - start baking at 500F on a pizza stone, and put a cup of boiling water in a tray in the oven. When you put the loaf in, spritz the sides of the oven with water, and repeat that at 30s, 1m and 1m30s, then turn the oven down to 450F to bake. The steam helps keep the crust moist for a while, which slows down the coloration, and allows the bread to spring in the oven.
Thanks for writing up the recipe!
