- Combine all the ingredients, except the oil, in a bowl. 
- Season with salt.  
- Gradually stir in 4 tablespoons water to make a thick, stiff batter. 
- Heat enough oil for deep-frying in a kadhai or deep frying pan (skillet) to 180°C / 350"F, or until a cube of bread browns in 30 seconds.    
- Then reduce the heat slightly. 
- With damp hands, take a ladleful of the batter and flatten it into a 5cm / 2 inch round patty. 
-  Working in batches, slip the patties gently into the hot oil. 
- Deep-fry, turning frequently, for 2-3 minutes, or until the patties are golden brown and crisp.
