We just made up a bunch of sweet pickled ginger(amazuke).
It's an easy recipe -
8 oz. of ginger, peeled and sliced thin, 1 cup rice vinegar, 1/3 cup sugar, 1 1/2 tsp. salt.
Toss the peeled sliced ginger with the salt, meanwhile heat the pickle jar in some water to avoid cracking it when you pour in the hot vinegar/sugar mixture. In a small pot, place the rice vinegar and sugar, stir to dissolve the sugar and bring to a boil. Remove the warmed jar from its water bath, add about 1/2 inch of boiled vinegar to the jar and pack in the sliced ginger. Cover with remaining hot vinegar mixture. Allow to cool before covering and refrigerating - ready in about 1 week.
