This is another popular sambanda in the kota region. Sambanda is the best way to use up vegetable peels((heerekayi, in this case) after using the vegetable for other dishes(like heerekayi chatti or dal).
Probably this is The Sambanda(as in, people think this is what you are talking about when you say sambanda), while sorekayi chutney is a variation from the original. The procedure and spices are slightly different than Sorekayi chutney.
While in the first method, the flavors are more raw and fresh; in this method the flavor is more cooked. Here you roast and add some urad dal and dhania along with the ridge gourd peels and pulp.
Both the methods could be incorporated with any vegetable.
