To prepare the boondi: To the gram flour add soda bicarb and a little water. Mix to a thick batter. Divide into three portions. Add a colour each to the three portions. Heat oil in a kadai and deep fry the boondis in hot oil till done and crisp.
Add enough water to the sugar and simmer till the syrup reaches three string consistency. Add the coloured boondis to the syrup and soak them for about 10 minutes. Remove and keep aside.
