Our orange tree is covered in oranges. They're not quite ripe yet, perfect for sticky marmalade. Unfortunately, I barely made a dent (Michelle, would you like some?) After scouring the internet for recipes, I simply chopped up some oranges, added the same volume of water, boiled till the rind went soft, added an equal quantity of sugar (next time I would use a cup or two less) and boiled till the setting point was reached. It is sticky and sweet, and ever so slightly bitter. Yum!
