Place the jars in a heat-safe container large enough to hold all the jars and a sous vide circulator, and yes it's okay to stack the jars (I used an 8-quart stockpot in the photo above). Also, place the cooking vessel on a heat-proof surface away from children or pets.
About 21 pounds of fresh tomatoes are needed per canner load of 7 quarts.
