Boiling produces the most reliable results when hydrating large cereal grains for spawn production. Boil until the starchy core has turned from white to translucent, then dry long enough for the surface to roll freely, and free of moisture.
this process is the same for common large cereal grains used for spawn production: Wheat, oats, and rye berries.
load jars with approximately 3 cups, then sterilize in your pressure cooker or autoclave for 2 hours @ 15-18 psi.
Allow to cool overnight, then unload and inoculate. Jars must be at room temperature before inoculation, it's always advisable to allow cool-down to take place within the sterile environment of the sterilizer.
A note on soaking: Soaking does not soften, "hatch", or reactivate bacterial endospores. Soaking, if anything, can potentially trigger endo sporulation (spore formation). Boiling alne is sufficient to hydrate, ensure that grains are cleaned prior to boiling.
