I adore orange marmalade. It is so damn good. I have never made it though. I may get adventurous and make it at some point this fall, as everyone in my family loves it as well. Those little bits of orange and rind are a wonderful texture break from plain old jelly or jam.
2 pints of water for every pint of fruit
Take fruit and slice thin or cut into a small dice and remove all seeds. Measure out water and cover for 24 hours. Boil for 1 hour. When cold, measure the fruit and add equal amount of sugar and boil 1 hour longer until it jells.
