What temperature is the "warm" setting on a conventional oven? I'm making a rack of pork ribs and I want to try and cook them as low and slow as possible, with time not really being an issue. Just wondering if the warm setting is enough to do the trick. I'm cooking the ribs from frozen, with two cups of water in a covered pan and some liquid smoke.
The collagen in the ribs needs to get to a temperature of about 160 F to start breaking down into water and gelatin.  If your oven can be set as low as 175 or 180 F on a normal bake or convection bake setting that is probably a better alternative unless you have access to an oven thermometer and can measure what temperature the warm setting on your oven attains.
