I have never heard of canning butter, that is interesting..If you ever have the time, could you send me your receipe... GG
I was going to write it up (or find it, it’s somewhere on my computer) for you but today got away from me.
Freepmail or ping me tomorrow or whenever you have time to remind me in case I forget.
I’m going to do another batch soon. It’s really simple and works if you do it right, I do water bath canning every year so I’m familiar with basic canning methods and so on. You don’t water bath this, though. But it seals and keeps well when done properly.
They say you can can cheese, too! Never tried it but maybe I will just for educational purposes.
