Semolina (shevaya) do not get spoiled for a very long time. But kheer made from them spoils easily. Why is this so?
उत्तर
Semolina is made by drying them in the sun. They do not have moisture in them and hence can be stored for a long time. They do not spoil even after storage. But kheer is made using milk. Milk is highly perishable; that is, it can get spoilt soon. Therefore, kheer spoils quickly.
