First, cut the green grape branches little by little with scissors

I'm going to make it with the skin, so it's good to wash it clean.
Sprinkle half a cup of flour or baking soda evenly
The starch in the flour is absorbent, so it sticks to the soil and dust easily
Let stand for 10 minutes or so

Rinse it in water

To sterilize, put 3T of vinegar in water and soak in vinegar water for 10 minutes

Wash it thoroughly and shake off the water

Grind it with the skin
If there's a lump, it's good to chew

Pour the same amount of sugar, 400g, to the same height

If you leave it in the refrigerator as it is, it becomes delicious green grape juice :) Mix it with carbonated water and drink it to become a cool green grape flavored cider :)

To make jam here, add 1T of lemon juice and 1t of salt and mix them all
I think you can make half with jean and half with jam :)
Reheat 9 minutes in a rice cooker for 3 times (about 30 minutes)
Put it in a pot and boil it for 30 minutes while stirring

It becomes more and more transparent and becomes sticky jam. :)

When it's completely cold, the skin melts and the jam turns orange
Enjoy your meal!:)
