I have a vacuum food sealer, there is a canning jar adapter for vacuum sealing dry goods in jars. The lids have to be kept warm to ensure a good seal. The oven method sounds easy too. Thanks for posting!

I use the adapter all the time and never heard of keeping the lids warm for a better seal. I could use a better seal. What do you do to warm the lids?

Thanks for the tip.

Oh yeah, well I use Neon gas and replace all gas in the container with the inert neon gas then i place a rod of cobalt-60 into the container.

My food has a shelf life that is cobalt 60’s half life!
