What is a Kumquat?
Kumquats are one of the smallest members of the citrus family ( Rutaceae). They are said to be native to China.
Kumquats can also be found in North and South Korea, Middle East, U.S, Japan and some other countries.
What sets them apart from other members of the citrus family is that Kumquat outer skin can also be eaten and it’s sweet.
There are 3 main varieties of Kumquats:
- Nagami Kumquat: football-shaped and most common in markets.
- Meiwa Kumquat: round shaped and one of the best.
- Fukushu Kumquat: a little bit larger and has a thicker skin than the other 2 types. Very sweet kumquat.
What does a Kumquat look like?
Kumquat is about the size of an olive or a little bit bigger and has the appearance of a mini oval-shaped orange. It’s also one of the smallest members of the citrus family.
What does a Kumquat taste like?
One big difference between an orange and a Kumquat is that the sugar content of Kumquat is actually in its outer skin.
The inside juice of the Kumquat has a sour taste similar to a lemon and the outside skin is sweet so it has a sweet and sour taste.
However, if you were to eat them raw (which you can) like any ordinary fruits, you’ll taste the sour part of the Kumquat as soon as you pop it into your mouth but it will get sweeter as you continue to chew on its skin.
In simpler terms, Kumquat tastes like a sweet and tarty orange.
Kumquat Benefits & Uses

However, if you want to grow it from its seed, the germination process for Kumquat seed is the same as any other citrus tree.
You should only water the Kumquat tree if you can see that it’s dry. You can feel the soil with your hand to see if it is and water accordingly.
Pruning the tree can slow down the Kumquat trees from fruit bearing.
If you wish to grow your Kumquat tree in a pot, add some gravel or stones to help the water to drain.
Use fertilizers recommended for citrus trees.

Kumquats taste fabulous when eaten raw or cooked. You can literally pick them from the tree and pop them into your mouth or enjoy them in Kumquat Marmalade, chutney, candies and so on.
As mentioned earlier, you can feel free to eat the outer skin of the Kumquat because that’s where all the sweetness of the fruit is. Sweet outer layer and tarty inner layer.
Don’t forget to throw out the seeds though unless you’re planning on germinating them to grow Kumquat trees.
