I got a dried beans canning recipe off here many years ago now and have canned them twice now and now I can't remember HOW MUCH of a head space I need on them. I'm suppose to presoak them the night before it says in the recipe but it didn't give the head space to leave, once filling the jars with the water. Since they ARE presoaked they shouldn't swell any. I just can't remember how much I left before. Having fits with my thyroids and it's messing with my memory. Hoping someone might be able to tell me. I was thinking maybe just fill to the neck of the jar so that would leave like an inch headspace.
