We usually use sugar powder to make biscuits, cakes, etc. Selled in supermarkets, sold online, are expensive. The dry mill in its practical cooking machine can grind the sugar into powder. About 30-60 seconds is ok! After the screen is more uniform. Later, I was lazy, and after almost dry grinding, I let it cool and enter the bottle.
Grind the powder into a powder with a dry mill. If you want to pursue perfection and fineness, just pass the screen.
Perfect icing sugar without additives ????
The freshly ground powdered sugar is hot and must be allowed to cool before it can be packed into the bottle.
