Orange jam!!?!

Home-made jam in our house is referred to by colour. Red jam - strawberry, Blue jam - blueberry, Green jam - kiwi fruit, Purple jam - blackberry (I know this one doesn't quite fit)...so when a friend gave me a bunch of her beautiful cumquats over the weekend I began to wonder whether I could 'sell' cumquat marmalade to the two widgets as 'orange jam'?

I'll let you know how I get on!
