Rinse the dried soy beans and place them in a 1-2 quart bowl. Add enough water to cover the beans by about 3 inches. Soak overnight or for 8-10 hours.
Rinse the re-hydrated beans and drain. Pour 6 cups of water into the basin of a soy milk maker (up to the line), add the soy beans, attach the top and plug in the cord. Press the "soy" button. See below for stove-top directions.
When the machine has finished the cycle, remove the cord and remove the lid. Pour the soy milk through a seive to remove the soy bean pulp (okara). Catch the milk in a large cup or bowl. Add the salt and flavorings if desired. Let it cool and put it in a glass pitcher or container. It will keep for about a week.
