I love this marmalade - the tart bitterness of the grapefruit juxtaposes the sweetness. This is ideal on a slice of buttered breakfast toast (with tea).

Ingredients Nutrition


  1. Using vegetable peeler, remove peel from 2 grapefruits (coloured part only) in long strips.
  2. Cut peel into fine julienne.

  4. Drain, rinse under cold water, and drain again.

Made this on Sunday and it is pretty good! I tripled the recipe and zested the peel rather than sliced it because I wanted fine-cut marmalade. The grenadine gave it a great pinky orange colour and I got just over 7 cups of marmalade.

Edit: Since I have made this several times, I think that I should change my review to 5 stars. I just love it. Thanks! ***My Mom sent us a box of grapefruit for our anniversary. After a while, I started looking for something to do with them! Since my dh loves grenadine, thought I would try this. It turned out lovely. This was my first time making marmalade. I later used some of the marmalade to make Orange Marmalade Cookies which turned out very well. Thank you very much for a lovely recipe.
