One of the challenges for me when canning is determining how
much produce I need, or number of jars will I get from what I have on hand? I don’t have a crystal ball, and since most
of us did not grow up canning as a norm I need a reference point. I found that point in an old canning book my
Mom recently gave me. Ball
Blue Book The Guide to Home Canning and Freezing, dated 1983. I bought
the newly released version of another, and I find it more difficult to use than
the old standard she gave me.
Now, how to estimate the number of jars needed. It would really stink to have all the produce
on hand, and not have enough jars or lids, so planning is essential as far as I’m
concerned. I guess there’s always the
freezer or dehydrator as back up, but I like to be prepared and know what I’m
getting myself into.
Here’s a rough list of produce, and the average weight
needed for a 1 quart jar. Please note,
it will depend on how you pack the jars.
Is the product sliced, chopped, left in half, etc.? But this should give you a great idea of what
you’ll need to plan for.

We’re getting ready to start our
fall garden. We were a bit delayed due
to an issue at The Compound a couple of weeks ago, but hope to get the
seedlings started this week, so I can do some more canning.
