To make soft and porous Dahi Bhalla, ensure your urad dal batter is properly fermented and aerated, and fry them at a moderate temperature. Soaking the fried bhallas in warm water is also crucial.
Detailed Explanation:
Achieving soft and porous Dahi Bhalla involves several key steps:
- Dal Preparation: Use good quality urad dal (split black lentils without skin). Wash the dal thoroughly and soak it for at least 4-6 hours, or preferably overnight. This helps in proper grinding and fermentation.
- Grinding: Grind the soaked dal into a smooth, fluffy batter. Use minimal water while grinding to avoid a runny consistency. The batter should be thick and airy.
- Fermentation: This is the most crucial step. Ferment the batter for at least 6-8 hours, or overnight, in a warm place. Fermentation introduces air into the batter, making the bhallas light and porous. You'll notice the batter has increased in volume and has a slightly sour smell.
- Aeration: Before frying, whisk the fermented batter vigorously for 5-7 minutes. This incorporates more air and ensures the bhallas are light. You can also add a pinch of baking soda or fruit salt (Eno) at this stage for extra fluffiness, but don't overdo it.
- Frying: Heat oil on medium heat. Frying at too high a temperature will cook the outside quickly while leaving the inside raw. Gently drop small portions of the batter into the hot oil and fry until golden brown on all sides.
- Soaking: Immediately after frying, drop the hot bhallas into warm water. Let them soak for at least 20-30 minutes. This allows the bhallas to absorb water and become incredibly soft. Gently squeeze out the excess water before serving.
Pro Tip:
To test if your oil is at the right temperature, drop a tiny piece of batter into the oil. It should rise to the surface slowly and steadily. If it browns too quickly, the oil is too hot; if it sinks, the oil is not hot enough.
