Why do we get a smell when cooking cabbage ?

Today morning my mother was preparing food for the afternoon lunch . She was preparing cabbage Sambhar . So she had to cook the cabbage in an open vessel . As the cabbage pieces were boiling , I started to get an unpleasant smell which made me little uncomfortable . I began searching for the cause of smell .


Then I found out that the smell is the result of hydrogen sulphide gas that has been released when the cabbage is cooked for too long . The longer the cabbage is cooked , that much stronger will be the odour .



If we want to eliminate this odour , cooking the cabbage quickly in an open pan is one of the option . But the smell is not too hard to tolerate .
