Found this interesting recipe @ www.epicurious.com:
      2 lbs tangerines, each cut into 4 wedges
      1 lemon, cut into 4 wedges
      5 C. water
      2 vanilla beans, split lengthwise and crosswise
      3 1/2 C. sugar

      Cut tangerine and lemon wedges crosswise into 1/4 inch thick slices. Discard seeds from fruit. Transfer fruit to large bowl. Add 5 C. water, covering fruit. Cover bowl w/plastic wrap; let stand at room temp. 1 day. Transfer fruit mixture to heavy large pot. Scrape seeds from vanilla beans; add beans. Bring mixture to boil. Reduce heat and simmer until rind is very tender and fruit begins to fall from rind, stirring occasionally, about 1 hour 15 minutes.
      Remove from heat. Add sugar; stir till sugar dissolves. Boil gently until mixture is 210F, stirring occasionally, about 1 hour 20 min.
      Divide vanilla beans and boiling hot marmalade among four 1-cup jars. Cover tightly and refrigerate up to 2 months

      P.S. Couldn't I seal them in the jars and BWB them for about 10 minutes??? What do you think?
