FAKE FLEISCH

First, you take a dry mixture of soy-protein powder and wheat flour, add water and dump it into an industrial extruder, which is essentially a gigantic food processor. (You have to climb a ladder to get to the hole at the top.) At first, the mixture looks like cake batter. But as it's run through the gears of the extruder and heated to precisely 346°F (175°C), the batter firms up and forms complex striations. It took Hsieh and Huff many years to get the temperature right, and it also took years to discover how to cool the soy cake very quickly, before it could melt.
