When winter comes around I start missing fresh produce.   While the markets have some produce I live in an area where the farmer’s market is closed because nothing grows in the snow.   However, when I think of winter fruit I often think of citrus.

Sweet and tangy Grapefruit Marmalade

Oranges, lemons, and grapefruits fill the stores in the winter months and have a cheaper price tag because they are so plentiful.   I often buy oranges to take with me to work for a snack or as part of my lunch.  They are a healthy and easy snack to eat during the day.

Last week grapefruits were on sale at the local market.  I’m not a huge grapefruit fan but my husband enjoys them for breakfast so I bought a few.   Once I got home I couldn’t help looking for grapefruit recipes.  I found one for Grapefruit Marmalade that sounded really good.

Everything you need to make a delicious sweet and tart Grapefruit Marmalade.

While I don’t like grapefruit on its own I do like it when it’s in food.  I feel like it really gives desserts, jellies, and jam and sweet and tart flavor that is delicious.  So I left one grapefruit for my husband and used the rest to make marmalade.

It turned out really pretty.   It had an orange and pink color to it with pieces of the grapefruit right in the marmalade.  Make sure to boil the grapefruit for long enough that the bitterness comes out of it.  I suggest 90 minutes but you can go longer then that.

Love this sweet and tart Grapefruit Marmalade on my toast in the morning to brighten my day.

The resulting marmalade is delicious!  It’s sweet but tart and has subtle flavors of vanilla and cinnamon.  It’s really good on toast and I think it would be great on top of pancakes too!

Love the sweet and tart flavor of this Grapefruit Marmalade studded with vanilla flecks.


  • 2 lb. grapefruit (about 3 large)
  • 5 c. sugar
  • 6 Tablespoons bottled lemon juice
  • 1 vanilla bean, cut in half lengthwise
  • 1 teaspoon cinnamon


  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 1/4 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 1/4 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.
