Hi Mat,

Like Flummery said you can use the quince recipe for chaenomeles japonica ( cido ). I have 5 bushes of them ( they are in their seconde year now ) and I made marmalade from Cido too ( I used the marmalade not just for bread but as sauce for pan fried chicken, meat balls, bake fish ...).
Pick them when it is yellow and still firm (harvest from september onward ). It does takes lots of work with peeling and removing seeds ( the flesh is not that much ). I made my marmalade by simply boiling them with some water ( enough to cover the fruit or a bit over it ) and some sugar( depending how sweet you like it ). Once the fruit is soften by boiling, use potatoes stamper to mash them up and add some small amount of vanilla and cinnamon and let it cook for another minute, pour it in bottles... ready to be eaten ( as sauce or for bread spread ) Bon a petite.

Momol
