I feel pretty dumb asking this, but I haven't been able to find anything that tells me exactly what to do. I just bought a Kuhn Rikon pressure cooker and Ohsawa pot. the pressure cooker came with a trivet like piece that fits into the bottom. Do I add water (if so, how much) to the bottom of the pressure cooker with the trivet in it AND add water to the rice in the Ohsawa pot? If so, for short grain brown rice what proportions would I use? Many thanks to anyone who can help me. Pam
