This is a great step-by-step tutorial on how to can Cherries.
I love picking my own fruits and berries so this was a great help to me. I am not an experienced canner so following this guide definitely helped.
I have made a promise to myself to start canning more as it is great for storage and fresh in season is always better all year long.
You can leave the cherry pits in or take them out, I would prefer them taken out but it is really time consuming so it's up to you.
