This jam has placed 1st and 3rd at the LA County Fair (that’s not a little one)!
I think leaving them on for a longer period of time is not good for next year’s production, but I’ll have to see how next year’s crop fares in order to test my theory.
Two weeks ago, I flew to Chicago and then drove to Michigan to visit my parents. I decided to bring them a little bit of California sunshine, so I brought them some kumquats, Meyer lemons and navel oranges from my trees.
My mother usually makes kumquat marmalade, and everyone who has tried it absolutely raves about how marvelous it tastes. However, there is much more work involved in kumquat marmalade, due to having to slice up these tiny citrus fruits. Here’s the recipe.
Mum decided to have a go at an easy kumquat jam this time. She didn’t use a recipe, but I told her I wanted to know the amounts so that if it was really good, I could share it with you. Well, she kept track of the recipe and it was a hit! I’m not the biggest fan of marmalade, but I really like this easy kumquat jam recipe! I bet you will, too.
What are Kumquats?
Many of you have probably never heard of, or seen a kumquat. They are tiny (one or two inches long) citrus which have edible skins. The skins are sweet and their juice is sour. They have seeds just like any other citrus fruit. However, kumquats are considered a superfruit. “Forget pomegranates—start popping kumquats. The tiny little olive-sized citrus fruits are full of disease-fighting antioxidants, which are contained in their sweet, edible skin.” –Prevention.

PRINTABLE RECIPE BELOW
January 2021 ~ I’ve had two people email me in the last week to say their jam tasted amazing, but it didn’t set. The first lady reboiled her jam, and she said it turned out perfectly. I’ve just emailed the second lady to tell her to reboil hers, too. Here’s what I think the problem is: the jam is not boiling hard/fast enough after the sugar is added. It should be at a rolling boil. The other problem is that the jam should not be removed from the heat until it reaches the correct temperature, or passes the plate drip test. This recipe is solid, just follow the directions and you will have perfect results.
Ingredients
- sugar
- water
- kumquats
Special equipment: clean jam jars
Directions
Prepare the Kumquats
Place the seeds in a small, food safe bag or some cheesecloth. Tie the top.
Put the sliced kumquats and water in a heavy pot on the kitchen counter. Let the seeds hang into the kumquats and water and place the lid on to keep the top of the bag from submerging. The seeds contain pectin which helps the jam to set.
Allow to rest for a minimum of 8 hours (there is no cooking yet).
Remove the bag and squeeze as much as you can from it (this is the natural pectin which helps the jam set). With a large bowl nearby, measure the amount of jam mixture that you have in the pot with cups. This number of cups is a better measurement of how much sugar you should use.
Example, if have 9 cups of mixture, use 9 cups of sugar. My mother always uses a little less, but if you like it sweeter use the same amount.
Cook the Kumquats
Move the pot to a cooktop over medium heat. Slowly bring to a boil, stir and reduce heat to simmer for about 20 minute or until the rind has softened. Stir occasionally and don’t allow the jam to boil too hard so that it may stick.
Next, add the sugar; stir and bring to a rolling boil (do not simmer) for approximately 30 to 45 minutes. The less sugar, you use, the longer it will need to boil to reach the setting point (220˚F / 105˚C).
The jam is ready when it congeals when dripped onto a plate from the freezer, if you do not have a candy thermometer. Do not stop cooking the jam after the time frame I’ve given; that’s simply an estimate (how long mine took to set). You must rely on a thermometer or the plate test.
Next, remove the pot from the heat and using an immersion blender, carefully blend the jam.
Pour the Kumquat Jam Into Jars
Rinse the jam jars and lids with boiling water then immediately ladle the jam into the jars. It’s helpful to have a widemouth funnel, but not necessary. Clean the rim with a damp cloth and put the lid on tightly as soon as possible. Finally, set aside and allow to cool completely, and refrigerate.
Process in a boiling water bath if you want to keep the jars in the pantry. If you’ve never made jam before, the lids will make a popping sound and the middle of the lid will be concave once sealed. If this does not happen, you must refrigerate the jam.
Use the jam as desired. Isn’t this truly an easy kumquat jam recipe?

Loved this jam! Cannot wait to make it again!
So many people say the same, thank you, Rhonda!!
thoroughly enjoyed reading your recipe. thank you.
Hello from Southern Alabama! Trying this recipe today. How long will the jam keep? If the lids pop, then I can store it, correct?
Thank you, looking forward to making marmalade for the first time!
Hi Julie, sealed jam keeps for years, but realistically use them within 2 years. To answer your second question, when the lids pop they’ve sealed, but according to US health standards, the jars must be boiled to seal them. Let me know how it goes!
This is how I’ve always used to make my Kumquat Marmalade and it’s delicious although after cooking the Kumquats I drain them out as I don’t like peel in my Marmalade, I usually use slightly less sugar as I like it slightly tart.
Oh, did you know that the peel of the kumquat is the part that’s sweet? You may enjoy this recipe.
The peel has the highest concentration of the good stuff; flavones and other amazing substances – anti-inflammatory, anti-cancer, etc.

Absolutely 100% correct, JT!
Made the kumquat marmalade and first time around it too wasn’t set. So I boiled it again and, as you say, it came out great. Question: I couldn’t find the info as to when to take out the kumquat seed sachet out of the mi . I took it out after adding the sugar, but when it wasn’t setting, out the sachet back in. When do you take it out?
Thanks!
Hey Christina! Looking forward to trying out this recipe! Just wanted to ask what amount of sugar did you use to get the award? Was it a little less than a cup or the recipe that’s on here? Thank you
