This recipe can be made larger if you want to. The ingredients below make almost 2 kg of marmalade, which I find is the most I can make in my large pot, but if you have a giant jam pot you may be able to make more… and also lucky you, I would love a jam pot. But the tiny kitchen does not allow for such luxuries.
Add 600g raw sugar and 200ml pure grapefruit juice to your pot.
Grate the rind off all the oranges. Nice thick bits of rind are just the best ever in marmalade. Then add the rind into the pot too.
Just a couple of last thing to note… as the marmalade is not high in sugar it doesn’t set quite as solidly as ones you buy in the supermarket. Don’t worry! That’s fine. It will be a thick jammy consistency. Yum.
Store in the fridge and it will last a year.
