Cover the bowl with a plate or cloth, and allow the berries to soak at normal room temperature overnight or for about 12 hours. The berries will soak up a considerable amount of water. Drain the berries in a colander, cover the colander with a plate to prevent the berries from drying out, and set it in a place where the sun won't shine on it. Rinse the berries about 3 times a day, and they will soon begin to sprout.
Growth depends on moisture and temperature.
Grinding the berries is the next step. Probably the Essenes ground them up with rocks, but that isn't required. After grinding, dump the mushed up grain onto a clean work surface. Squeeze and knead the grain for about 10 minutes, and then form up 2 small round, hearth-style loaves with your hands. Sprinkle an insulated cookie sheet with a little bran or cornmeal, and put the loaves on it.
