The surface of milk is not sticky. If you put a spoon on it, it won't sink. Later, after studying, I found that there are many details to pay attention to in every step from raw materials to temperature. Ginger is fresh ginger, ginger juice must be made, fresh extract juice. There will be white sticky precipitate in ginger juice, which is the key to coagulation with milk protein-water-soluble protein, and it will precipitate at the bottom of the bowl, so when bumping milk, you must stir ginger juice first and then bump milk.
Milk should be full-fat milk, ginger should be fresh, and ginger has no juice. Ginger juice is condensed by proteolytic reaction of casein from full-fat milk and ginger. The temperature of hot milk should be controlled between 70 and 80 degrees, and the temperature can be accurately controlled with a thermometer. Turn the electric ceramic furnace to the maximum power, heat the milk and add the white sugar and stir until it is completely melted. About 2 minutes, there are dense small bubbles in the middle of the milk, and the temperature is about 82 degrees. After cooling for about 30 seconds, the milk can be beaten when it is cooled to 70℃-80℃.
