Grapefruit Marmalade - Does Fruit Have To Be Ripe?

I know that grapefruit has more pectin at that point just before it becomes ripe? I have been given a large bag of grapefruit in this condition. Will they be OK for making marmalade or will it turn out beautifully set but too sour to eat?

It could turn out quite tart, but I also use some unripe ie not quite ripe grapefruit too in mine, with a mix of ripe ones.

Yes, you'll have the best marmalade ever. This is how my mother made marmalade every year - just using slightly unripe grapefruit.

Gosh that was a confusing message wasn't it.
I meant that the best marmalade (imho) is made with slightly unripe grapefruit.

Oh that is excellent. Thank you both so much. I have not made much in the way of marmalade. I do a lovely one that someone posted on here using oranges and lemons but never a grapefruit one.

One more question if anyone would be kind enough. I know that most of the pectin is found in the pith. It seems logical, therefore, to make my marmalade with the pith as well as the skin. Would I be correct in that assumption? Aunt Daisy hasn't said anything on the subject.
