2 part lid

Q: Can someone tell me the purpose of these 2 part lids that you
sometimes see on jams and salsas. Why not just use the regular lid?

That's a canning jar. The inner lid has a rubber ring to help hold the seal while the outer ring adds extra security. If you want to reseal (so as to "preserve", as in preserves you put on your toast), you can use another inner lid and the same outer lid.
