How to make icing

Take an egg while in a bowl. Add 250-300 gms of icing sugar and beat it. Remember to add sugar in small amounts slowly to the egg. If the mix appears too watery. Keep adding more icing sugar to it. Keep beating the mix until it appears to be glowing and becomes firm. Check by taking out some mix on the spoon. If you want to give your icing a flavor, you can add cocoa, coffee or vanilla powder
