Center a new lid on a jar of sauce, apply the ring band, and tighten it fingertip-tight.
Carefully place the filled jars onto the rack in the canner, making sure the water covers the jars.
Place the lid on the canner and bring the water to a full, rolling boil.
Boil for 10 minutes before removing the jars to a tea towel
Let the jars cool undisturbed for 12 hours to allow the seal to set.
After cooling, check the lids by pushing down on the center, if the lid doesn't move, it's properly sealed.
