'McMenu: Do-It-Yourself McDonald’s Restaurant Recipes' is an alledged authentic list of recipes of McDonald's food products. It teaches you how to choose the right beef patties, how to cook them, how to toast the buns and much more. There are recipes for McDonald's icons such as the Hamburger, the Quarter Pounder, the Big Mac, Filet-O-Fish and even the french fries. From the HTML version of the PDF file:
Peel the potatoes. In a large mixing bowl, combine sugar, corn syrup, and hot water. Make sure the sugar is dissolved. Using a French fry slicer, cut the peeled potatoes into shoestrings. The potatoes should be 1/4" x 1/4" in thickness, and about 4" to 6" long. (You can do this with a knife, but it is a lot of work)Here's the PDF file (hosted by Junkheap) for download. These recipes are based on the old McDonald’s production methods of the 50's, 60's, and 70's.
Place the shoe-stringed potatoes into the bowl of sugar-water, and refrigerate. Let them soak about 30 minutes. While they're soaking, pack the shortening into the deep fryer. Crank up the temperature to "full". The shortening has to pre-heat for a very long time. It will eventually liquefy. After it has liquefied and is at least 375°, drain the potatoes and dump them into the fryer. (be careful, it will be ferocious)
