Got this good info from someone on how to make:
Whole Wheat Cereal

Take 2 cups of wheat kernel and 4 cups water in a crock pot. (Basically 2-1 ratio.) Simmer on high for approximately 2 hours. Turn off the crock pot and let it sit overnight untouched. (Don't open the lid.) Then throw them in a container and place in the refrigerator. (When I did this, the kernels on top looked dried out and the ones on the bottom where moist, but I mixed them around in the container and they all looked moist a few hours later.) It says they'll last appx. 10 days in the refrigerator.

I started them in the early morning, simmered on high for 2 hours, and then left them turned off on the counter for appx. 7 hours. I think I used them that night.
