Use gram flour for authentic texture and flavor. Ensure oil is hot enough to get perfect crispiness without absorbing too much oil. Don't overmix the batter to keep texture light and crunchy. For extra heat, add green chilies or cayenne. Maintain consistent bhaji size and avoid overcrowding for even frying. Serve fresh and hot. Variations include adding grated vegetables or swapping herbs. Bhajis can be baked as a healthier alternative and stored refrigerated or frozen for later.
