I normally spoon my marmalades on morning toast, but after I made this batch, I had cleaned up the kitchen and was going to reward myself to a nice bowl of split pea soup for lunch with some Comté cheese and – like most good ideas (and a few of the bad ones) – it suddenly occurred to me that the tart marmalade might be nice with the nutty cheese I was cutting into batons. Print Kumquat Marmalade Many of the little rings of kumquats will, unfortunately, come apart as you cook the marmalade. Tie the seeds from the lemons and kumquats securely in a piece of cheesecloth and add the seed sack to the pot along with the sliced kumquats and water.
