This recipe came from a sure-Jell pamphlet dated 1974. As a new bride then, I was inspired by my sister-in-law to try canning, and I've been "putting up" ever since. I had marked this recipe to make it, but never did. I wish I hadn't waited so long! It is a great "morning" jam---wakes up you taste buds, but without the astringency of marmalade. Great on bagels!
