Prepare the popsicle mold (it hasn't been moved for half a year, and after cleaning, I cooked a pot of boiling water, and threw all the molds into it to scald and drain). At this time, the bean soup is still a little warm, so don't wait until it is cold and too sticky to mold! Cook slowly on low heat, add 200ml milk, one spoonful of condensed milk, two spoonfuls of white sugar, one quarter spoonful of salt, and appropriate amount of water starch, and simmer until thick. First, soak the red beans for about two hours, then add some water to start cooking. Add the right amount of sugar. I like to add rock sugar! Add corn starch in a small bowl, then add some water to make it boil. You can add a small amount of milk, and then stir it to make it melt. Pour the prepared starch into the red bean soup and let it cool.
When we take a flight, the meals served by flight attendants are usually packed in aluminum foil boxes, and dessert shops also use aluminum foil cups to hold cakes and puddings. This is because aluminum foil, as a metal, is easier to conduct heat and cold. Go to the supermarket to buy an ice cube bag, that is, a lattice in the bag, fill it with water and freeze it, and tear the bag when using it. The ice cube is also a round block. Naturally formed ice is called natural ice, and ice usually made by artificial refrigeration is called artificial ice, machine-made ice or industrial ice. There are many kinds of artificial ice, including industrial ice, edible ice, dry ice, etc. Then put cold boiled water, preferably pure water, into the ice compartment, and never use tap water.
