Gently heat the onions with salt in the olive oil in a heavy-based pan and cover the onions with some scrunched up dampened baking paper and a lid on top and cook for 1 hour till onions are carmelised and soft
Remove lid and paper and add the sugar, once dissolved raise the heat and keep stirring as the onions turn deep brown.
Add the red wine, balsamic vinegar and red currant jelly
The onion marmalade should be thick and you will get a clear trail if you drag your spoon through the mixture
ladle into sterilised jars
