Onion Bajji Ingredients
- Onion - I have used medium sized onions sliced slightly thick. It gives sweetness and soft texture inside the bajji. You can use big onions also.
- Besan Flour - I used as main base for batter. It helps coat the onion and gives structure. Use fine quality for better result.
- Rice Flour - I added along with besan. It gives crisp texture to the bajji.
- Red Chilli Powder - I have used it for colour and mild spice. It gives bright colour. You can use normal chilli powder also.
- Ajwain - I added for flavor and digestion. It gives slight aroma to the bajji. You can skip if not available.
- Cooking Soda - I added small pinch of cooking soda. It helps the bajji become soft and little fluffy. Do not add more.
- Oil - I used for deep frying the bajji for crisp outer layer and cooks evenly. Use enough oil for frying.
