Note: The amount of honey and white sugar depends on the weight of the kumquat and ginger. In a cheong, the weight of the sugars and the weight of the fruit should be at least a 1:1 ratio. In this case, the weight of ingredients is 405g, so we need to put in at least 405g total sugars. For my sugars I used 60% honey and 40% white sugar.
Mix the honey and white sugar together to form a paste.
In a clean mason jar, add a thin layer of sugar-honey paste. Put in a single layer of kumquat and ginger. Alternate between layers of sweet paste and fruit, finishing the final layer with the sugar. The sugar should totally cover the fruit. I usually find that I need to add additional granulated white sugar on top to totally cover the fruit.
Place the lid on the jar, and place the jar in a place away from direct sunlight, at room temperature.
The sugar should dissolve quickly in 2-3 hours, and the cheong will reduce in volume. Stir the cheong everyday for 3-5 days to keep the top moist and prevent mold from forming on top.
Move the cheong into the fridge for long term storage. There is no need to stir daily anymore.
The cheong may undergo alcoholic fermentation. If fizziness or a hissing sound is heard when you open the jar, or the cheong tastes alcoholic-like, move the jar to the fridge to slow down the fermentation.
The cheong is ready to eat in 1 week but tastes better after 1 month or longer.
