Er, not exactly... steam?? My mom pours the jam in the jars while it's still hot and closes them... as they cool down they seal themselves.
As for tomato sauce, she puts it in the jars, closes them, then puts the closed jars in a pot, covers them in water, and boils the whole thing for half an hour, then leaves them to cool down. Hope it helps!
