*When you turn the steam release knob to Venting, do so very slowly, not all the way. Just push it over a little and let the steam out in slow, short bursts. If you open it fully and notice sauce spewing out, grab a long handled utensil and put the knob back over to the Sealing position. Then start again with shorter bursts. After a few times, you can open it fully and there will be less pressure, which will only have steam coming out.
