Thanks for the help and the ideas...............
I didn't weigh ingredients, the recipe used cup measurements. I didn't use a candy thermometer or do a saucer test, I just followed the recipe in Blue Ribbon Preserves by Linda J. Amendt. I haven't had any problems with any of her recipes in the past so I didn't think I'd have a problem with the marmalade. The recipe called for liquid pectin to be added, will the marmalade possibly still take a few weeks to set up with the pectin in it? I do see a candy thermometer in my future along with doing the saucer test.
