Karo keeps caramelizing

How long do you sterilize karo jars in a pc? I've heard 15-20 minutes, but when I do that, combined with the 15 minutes that it takes for the pc to get up to pressure, the jars always end up yellow. Is 15-20 minutes TOTAL pc time ok for sterilization?

make sure you have it well off of the PC bottom, the 15 minutes is the total time from the point of pressure to finish... I recomend that once you build the pressure to reduce the heat a little and all ow the 15 minutes...

Are you running the PC too high? I usually PC Karo at 12 p.s.i., compared to 15 p.s.i. for grtains, etc. Never have contams and have never had a carmelization problem. 12 p.s.i. for 20 minutes works well for me...

IF you use Plastic lids and the microwave...like 2 cycles of 4 minutes, its sterilised.

yeah... keep it away from the bottom. The high heat is what causes the carmelization. I double stack some ring lids under the stand off plate. Don't let the water touch the jars, even when it boils. Many people don't realize that a pot with a lid on it will boil at a much lower setting on your stove than an open pot without a lid. So play around with some water in your PC and gradually turn up the heat every 5 mins until you hear it boiling. Then that's the setting you'll want to eventually get to when you do some Karo.
