I've been tinkering with this recipe for several years, and I think I finally have what I want. The efficiency could have been better, but it was my first attempt at a decoction mash. One could probably get the same results from a step mash. Here it is:

Mash Notes
Used in some authentic German styles. Attempt to draw decoction from the thickest portion of the mash. Profiles vary. Some traditional German mashes use a long acid rest at 40 deg C. Also some sources recommend the decoction amount be given a 15 minute saccharification rest at 158 F (70 C) before boiling it.
