In the summer, there will always be people on the street alleys pulling the tricycle to sell the jelly, adding a spoonful of mint water, iced, cool, slippery, as if the hot weather has become milder.
Pour the white jelly into the container, add a proper amount of cold water and stir into a paste.
Add water to the pot to boil, then add rock sugar to melt (salt can be added according to personal taste)
Pour the white powder that has been stirred beforehand into the pot and stir constantly. Cook for 2-3 minutes in medium and small heat.
Turn off the heat and cool it into a paste.
Unsweetened white jelly is tasteless and can be added together with milk tea, honey water, brown sugar water, etc.
