That sounds great, @catdaddy. I am so looking forward to kumquat and Seville / bitter orange season, so I can make marmalade.
I almost made a calamondin marmalade like you a few weeks ago; I was at the store with a half-filled bag in hand, but then someone who works there had me try one and indeed it was very sour and not as bitter as I would have liked, so I passed. But I regretted it a bit. I think it would still taste very nice.
