STEP 2/7
Remove the stem of the plum, wash it clean with soda, and drain it on the tray,
STEP 4/7
You can put plum and sugar in the bottle alternately, but the more sugar melts, the lower it sinks, so the sugar in the container all at once
If you put sugar while shaking the bottle because it doesn't fit all of it, the sugar won't melt well later, so if you don't have all the sugar you need to put in, add sugar little by little, two to three days. The sugar melts little by little from the bottom, and the large amount of sugar sinks and creates space.
STEP 6/7
Lastly, put fructo oligosaccharide and put sugar in the mouth of the bottle again, seal it, and store it. It's better to take out the plum kernel after about 90 degrees, roll the bottle in the middle and melt the sugar.
