Boiled Rice Powder Dosa is a popular South Indian dish made from fermented rice batter. It is a thin and crispy pancake-like dish that is easy to make and delicious to eat. The dosa is made by mixing boiled rice powder with water and allowing it to ferment overnight. The fermented batter is then spread on a hot griddle and cooked until golden brown. It is usually served with coconut chutney and sambar, and makes for a perfect breakfast or snack option.
