F and passes the plate test. Funnel finished marmalade into prepared jars. Wipe rims, apply lids and rings and process in a boiling water canner for 1. When time is up, remove jars from canner and let them cool on a folded kitchen towel. When jars are cool enough to handle, remove rings and check seals. Any unsealed jars should be refrigerated and used promptly.
I like this marmalade rolled into crepes or stirred into Greek yogurt. How would you use it?
