Put the milk, sugar and egg yolk into the pot and stir well. Heat the stirred milk in a small pot with low fire until bubbles appear, add milk powder, and stir while cooking until the liquid thickens slightly.

Turn off the fire and let it cool. Pour the mixed milk into the ice cream mold (honey beans and fruits can also be put first), and tap the mold to make the surface even. Then cover the mold and put it in the freezer for more than 5 hours. When eating, it is easy to take out the ice cream by washing it with water or leaving it at room temperature for a minute or two.
