do not have regular classes Chandra. A group of four is what I need for a class. In case you are a group of four, I would be happy to have a class. The menu and time can then be mutually decided. Just to give you an idea, I charge Rs1000 a class or Rs3600 for four classes booked at one time. The class lasts about 3 hours and you have to do the cooking yourself. The class eats what is cooked at the end of the class. So in case you are interested, you can write to me.
You cannot make icing sugar at home. It is processed in such a way that it has no grains at all. It is only a matter of choice to have strawberry icing on vanilla cake.
