I made a major breakthrough in de-hulling (or should it be just 'hulling' in the sense that when you remove peas from their pod or nuts from their shells, you're 'shelling'?). It hit me while I was bringing a pot of dry soybeans to a boil (in a boil-then-soak soaking), when the hulls of the beans, which, when dry, are white and brittle, soaked up the water immediately and pulled away from the still-dry beans. Now, I had read of tempeh producers using a wet-roller method to de-hull, so I grabbed a rolling pin and used it with some other ad hoc spacing implements to half-squish the beans as I rolled them, de-hulling them in the process.
