Love the sweet and tart flavor of this Grapefruit Marmalade studded with vanilla flecks.
Ingredients
  • 2 lb. grapefruit (about 3 large)
  • 5 c. sugar
  • 6 T. bottled lemon juice
  • 1 vanilla bean, cut in half lengthwise
  • 1 t. cinnamon
Instructions
  1. Put the grapefruit in a large pot and add enough water so that they float. Cover the pot and bring to a boil over high heat. Reduce the heat to medium and simmer for 90 minutes.
  2. Drain the grapefruit and transfer to a cutting board. Allow them to cool.
  3. Cut the grapefruit in half and discard any seeds. Slice the grapefruit into strips 2 inches long and ¼ inch thick.
  4. Prepare 6 half pint jars, lids, and screwbands by boiling in a boiling water canner.
  5. In a large pot combine the grapefruit, sugar, lemon juice, vanilla bean, and cinnamon. Bring to a boil over medium high heat, stirring frequently. Boil hard until a candy thermometer reaches 225 degrees, about 15 minutes. Remove from heat and let rest for 5 minutes. Remove the vanilla bean and stir the marmalade.
  6. Ladle marmalade into the hot jars to within ¼ inch of the rim. Remove any air bubbles and wipe the rims. Place the lids on the jars and screw the bands on to fingertip tight.
  7. Place in a boiling water canner with the lid on and process for 10 minutes. Remove from heat and remove lid. Let sit 5 minutes.
  8. Remove the cans from the water and allow to cool completely. Check lids after 24 hours to make sure they have sealed properly.
