A few years ago I made marmalade from some fruit I was given (limons, which I was told were a hydrid lemon/lime, and small grapefruit) - I think there might have been a lemon or two too - and a bought orange.

Geez, it's nice......the quantity I had made 14 jars, many were given away and I think I'm down to my last bottle. Himself doesn't eat jams, jellies or pickles so a jar lasts me a while.

I have also bought a jar of brown sugar marmalade at a farmer's market, all gone now alas - that was quite tasty. It was made with a mix of brown and white sugar, lemons and oranges (I think......don't have the labelled bottle so can't check) and was very nice.
