Mix corn starch, sugar and salt in a pot.
Slowly pour Shuhua milk into the pot bit by bit, and stir well while pouring.
Pour the egg yolk into the pot and mix well with the ingredients.
Heat the milk with medium heat, stir while heating, and soon there will be relatively boiling bubbles. Turn to low heat immediately, as small as possible.
Continue stirring for about 1 min to make the milk slightly sticky.
Then turn off the fire, pour in two drops of vanilla essence and stir well.
Pour the mixed milk into the popsicle mold, and then put it in the freezer for about 4 hours or more. When eating, wash it with water or leave it at room temperature for a minute or two, and the popsicle can be easily taken out.
