As any other marmalade, the proportion is always the same: per one pound of fruit, half pound of sugar or honey. I prefer to use coconut sugar but just in case I don't have it at home, you can use brown sugar.
If you are not vegan, honey will do great.
First, cut the fruit in small pieces or chop them in the food processor. Transfer to a small pan adding sugar and cook at low heat for about 30 minutes.
Transfer to a container when is cold and keep it in the refrigerator.
Enjoy!
