Navel Orange Marmalade

Here is another recipe to use up some of that citrus hanging out in your yard. We have a navel orange tree in our yard, usually I make a fresh freezer jam with them, but this year I thought I'd try to make marmalade. Mostly because hubby likes marmalade better. He really appreciates bitter drinks and foods. I have to point out, however, that navel oranges are sweet and not that bitter, so don't expect a jam that tastes like that from the store. It simply won't be as bitter. With all those caveats, this is a good jam and really pretty. I also give variations below for spiced orange marmalade and an even less bitter version.
