Help marmalade disaster

I have just managed to burn my oranges before I even start. I used the cook oranges first method and put the Seville oranges in preserving pan, added water and left to simmer but sadly for too long. There is a spoonful of burnt liquid and the oranges have burnt on the bottom. Is there anything I can do to salvage them or is this a chuck away job? Probably too late to get more Seville oranges too. I am mad at myself.
