Grapefruit Marmalade Recipe

User Rating 4 Star Rating (3 Reviews)


Recipe for grapefruit marmalade which makes 4 half pints.


  • 2 large grapefruits, thick skinned
  • 1 large lemon, thick skinned
  • 2 cups water
  • 4 cups granulated sugar


Peel grapefruit and lemon; cut away inner white part of peel, leaving rind and white pith. Cut rind into slivers 3/4 inch long and 1/8 inch wide. Chop fruit coarsely, reserving juice.

In an 8-quart nonreactive heavy kettle over moderately high heat, simer rind, chopped fruit, reserved juice and water, uncovered, 10 minutes. Pour into a large heatproof glass bowl and let stand, covered, in a cool place overnight.

Return mixture to kettle. Add sugar and set over moderate heat. Insert a candy thermometer and bring to a boil, stirring until sugar dissolves. Continue boiling, stirring occasionally, until thermometer registers 218 degrees F to 220 degrees F.

Remove from heat, skim off foam and ladle into sterilized half-pint canning jars, leaving 1/4-inch head space. Wipe rims, seal jars and process in a boiling water bath for 10 minutes (15 minutes for altitudes abouve 6000 feet). Remove jars from water bath, let cool for 12 hours and test for airtight seals. Label and store in a cool, dark place. If you decide not to sterilize and process jars, refrigerate marmalade and serve within three weeks.

Great, Member lberna

I used a combination of grapefruits, oranges, and lemons. I peeled the rind with a potato peeler. Used a mini-food processor to chop into small pieces. Boil the pieces in 3 changes of water to remove bitterness until tender - about an hour. Separate the slices of fruit, remove seeds, and rough chop them. Place equal parts of fruit and sugar in a pot. Do not add water. Cook uncovered for about an hour. Can check to see if the liquid is syrupy enough by placing some drops on a plate. Add the boiled rind pieces and stir well and cook for a few more minutes. Ladle into clean sterile jars. So good.
