What are Kumquats?

If you’re as unfamiliar with kumquats as I was, here’s a little information about them from WikiKumquats are often eaten raw. As the rind is sweet and the juicy center is sour and salty, the raw fruit is usually consumed either whole—to savour the contrast—or only the rind is eaten. Culinary uses include: candying, preserves, marmalade, and jelly. Kumquats have begun to appear as a martini garnish, in lieu of the classic olive. They can also be sliced and added to salads. A liqueur can be made by macerating kumquats in vodka or other clear spirit.

Place the kumquats and pulp into a food processor along with the chopped orange. Pulse until the kumquats are chopped more finely and somewhat liquefied.
Measure the mixture at this point and pour it into a bowl. Add equal amounts of sugar to the kumquat mixture (ie. 2 cups of kumquat mixture will need 2 cups of sugar). Mix in the sugar and add 2 tablespoons of lemon juice.

Microwave on high (uncovered) for 6 minutes, giving the mixture a chance to boil. Stir, and continue to microwave in 2 minute bursts (stirring after each burst) for a total of 10 minutes.
 
Remove from the microwave, stir and let cool at room temperature. The marmalade will thicken as it cools. Keep the marmalade in an airtight container; refrigerate for up to 2 months. Freeze for up to 6 months.

    I have been using this recipe for many times every year around the cumquart season.  I really want to thank you for developing such a wonderful recipe and presenting it in such a great way.  Thank you again.

    1. Lori Lange says:

      Thank you!

  2. Susan Duffey says:

    I prefer to use as little sugar as possible. One person said he reduced amount by 1/3… Can I use even less. . I do not mind if marmalade is a bit runny. Has anyone tried using less? 
    Thank you
    Susan

  3. John Boilton says:

    Great recipe even for a mere male. Worked perfectly however did find it somewhat sweet so reduced the amount of sugar by 1/3 the second time and found more to my taste.

  4. Roxie Kelley says:

    Is it okay to leave the jars at room temperature until their first opening? Even if it is a few months? I’m making about a dozen jars for a client and need to know if it is safe to store this way. Thanks.

    1. Lori Lange says:

      you’d have to go through the safe-canning process… I’m not really familiar with all of that, but there are many tutorials online.

    I grow both Meiwa and Nagami kumquat trees. The Meiwa fruit is sweet throughout so these are always fresh eaten by my family and friends. The Nagami fruit, with the sour/tart interior, were perfect for this recipe. Than you very much for this excellent tasting, easy and quick to prepare marmalade.

  6. Jon says:

    This looks very tempting, we have a lot of kumquats this year so I’d like to try it. As someone who has (apart from microwave lemon curd) never made jam may I ask why one needs to remove the pith and the ends of the fruit? I’ve seen pics of whole fruit preserve and they look yummy too!

    1. Lori Lange says:

      It’ll just be a little more bitter if you leave the pith in.

  7. Silvia says:

    This was the easiest and most delicious marmalade I ever ate. Thank you so much. I use it with toasts and i made a savory omelette and put it on top. it was great

    1. Lori Lange says:

      Nice to hear- thank you!

  8. Pam C says:

    I am going to make this tonight. I’ll be putting in canning jars with the seal. Should I put in the jars hot so that a seal will form?

    1. Lori Lange says:

      I’m not so familiar w/ canning, so I’m afraid I cannot help w/ that!

  9. Marty says:

    Made this and it is fabulous! Put into individual jars to give as Christmas gifts. Do I have to immediately refridgerate? Or can I give as gifts at room temp and suggest they chill immediately after opening?

    1. Lori Lange says:

      yes, room temp is fine and then ask them to refrigerate.

  10. MaryMc Cance says:

    My husband made this jam last night. No he does not normally cook!.

    It is delicious and so easy once you have done the preparation.

    Thank you we will be making this again.
