Ombol or Aum bol

A sour dish made either with several vegetables or fish, especially fish bones. The souring agent is usually tamarind pulp, unripe mango and sometimes amla or amloki is used. Curd, though a souring agent occasionally used with nonvegetarian dishes, will not be called ombol. It is served at the end of the meal as a kind of digestive, and to cleanse the palate.
