This recipe is for all fruits that you want to use. In my case, I chose kumquats cause I have a little tree in my house

Leave the sugar and the fruit together from 7 hours to 24 hours till you see that the sugar and the fruit juice have become a syrup. Then put it to slow cook.

While it is cooking you have to be mixing and smashing it with a wooden spoon to get the more juice that you can. You have to wait till it is thick and you can leave the amount of pulp you want

Finally, you have to put it in a glass recipient and when it is cold put it in the fridge. And voila you have a delicious and homemade kumquat jam
