what is the difference between caster sugar and normal sugar?!
Answers:
Caster sugar is a superfine sugar that is made from, normal sugar. It melts and dissolves easily.
If you don’t have any castor sugar on hand, you can make your own by grinding granulated sugar for a couple of minutes in a food processor

Caster sugar, also known as "super fine" or "bartenders sugar" has a finer grain than granulated sugar and melts very easily making it perfect for cocktails, whipped cream, and meringues.
