12 Steps to Canning Stewed Tomatoes

Step 10, Pressure Cook Jars

Just as soon as you have completed a batch, get them into the pressure cooker. Be sure to use the rack on the bottom with the proper amount of water, about 2 inches of water. Apply heat and when steam comes out of the top in a steady stream put the pressure top on. Bring the pressure up to 10 pounds and keep it there for the proper time. Tomatoes with green peppers require more time than tomatoes alone. Quarts will require more time than pints and be sure to allow for altitude. If you are at altitudes 1,000 feet of more you have to allow for more pressure. Make sure the pressure remains at least 10 pounds pressure.
