Steep 6oz's of the roasted, 8oz's of the flaked barley for 30-40 @ 160*. People will disagree but when I do extract and steep I will steep for an hour @ 154*. Anyhow add your extracts, 1-1.5lbs of honey and 6-8oz's of brown sugar, get it to a roll and dump 1oz-1.5oz of the hallertau's in. Boil for 45 minutes and throw the cascades in. Boil for 15 minutes, cool and pitch a neutral yeast. If you can come along some Carapils or Crystal, I would steep at least 1/2lb as well. I hope this works for ya.
