Yes, there is a military specification for making brownies. Reason's Hit and Run has a funny piece that Radley Balko (guest-blogging at Instapundit) uses it as a jumping off point to argue that government health care isn't likely to be cheaper or more efficient:
The Pentagon's brownie recipe is 26 pages long. Just grab a copy of document MIL-C-44072C and gather your ingredients: water that conforms to the "National Primary Drinking Water Regulations (Copies are available from the Office of Drinking Water, Environmental Protection Agency, WH550D, 401 M Street, S.W., Washington, DC 20460)," and some eggs in compliance with "Regulations Governing the Inspection of Eggs and Egg Products (7 CFR Part 59)," and you're ready to go!To the credit of Katherine Mangu-Ward over at Hit and Run, she recognizes that a 26 page military specification on making brownies for MREs (Meals Rejected by Ethiopians) isn't really as silly as it sounds. When you are contracting to have someone make several million brownies, the last thing you want is someone getting...creative in the ingredient list or manufacturing process. (And no, I wasn't referring to the herbal variant when I mentioned creative ingredients.)
It isn't just the U.S. government with detailed official specifications for how to make things. Here's the British National Standard for making tea. I shudder to imagine the British National Standard for black pudding. That might be too unpleasant to read.
