I have milk coming out of my ears, so I decided to can some up to use for next year's bottle babies. I did a batch with regular throw away lids & had 1 not seal. I did a batch with 4-Ever Re-Cap wide mouth lids & had 1 not seal. I did 4 batches with Tattler regular mouth lids & had 1 not seal. So there it is, my experiment. Had a failure with each kind I used. I think I will like the re-usable lids. I figured I'd try them on the milk. If it fails I can feed it to the chickens without losing much. I really couldn't tell a difference between the brands. They both worked well. I have more to do tomorrow.
