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.
This is wonderful! I used red grapefruit and got beautiful tangerine coloured marmalade. I had a bit of a panic when the lovely looking lemons I'd bought didn't yield enough juice. But I tied up all the pips, pith and unused rind in a muslin bag and added it to the pan, just to make sure there was enough natural pectin for the marmalade to set. I'll be making this again!
