How are candied ginger slices processed? A detailed explanation of the production method

Select fresh ginger, wash and peel it, then cut it into thin slices 3~5 mm thick. Prepare the ingredients in the proportions of 50 parts ginger, 32 parts white sugar, 4 parts powdered white sugar, and 0.25 part citric acid. First prepare a citric acid solution equal in weight to the ginger slices, heat it together with the ginger slices until boiling, remove the ginger slices, rinse them clean, and drain off the water. Then prepare a 62%~65% concentrated sugar liquid, add 0.15% citric acid, and boil until the sugar is completely dissolved. After filtering out impurities, add the ginger slices and boil again. Boil until the sugar liquid is thick and a drop forms a bead, then stop the heat and remove the ginger slices. After removing the ginger slices, sprinkle with white sugar and mix well, spread them out to dry in the sun for 1~2 days, or place them in a drying room and dry them at 40°C~50°C for 4 hours, and they can be dried into candied ginger slices.
