Rinse urad dal under cold water 3–4 times until the water runs clear. Soak in plenty of cold water for 6-7 hours (or overnight for a softer result). Drain completely.
Transfer the drained dal to a blender. Add ginger and green chili.
Add ¼ cup of water and pulse until a coarse paste forms. You want a texture that is neither a smooth paste nor chunky. Semi-coarse is the sweet spot: smooth paste makes oily pooris, too coarse means they won't puff.
Make The Dough
Scrape the paste into a large mixing bowl (or a parat). Add flour, sooji, oil, salt, fennel powder, coriander powder, red chili powder, dry mango powder, and hing to the bowl
Mix well to make a crumbly mixture.
Add water only a tablespoon at a time and knead to make a stiff dough. The dough must be stiffer than regular roti dough. If it's too soft, the pooris will absorb oil and won't stay crispy.
Cover with a damp cloth or cling film. Rest for 20–30 minutes. This relaxes the gluten, making rolling significantly easier.
After resting, knead for 1 minute more. Pinch off equal portions (slightly larger than a golf ball) and roll them smooth between your palms. This recipe yields about 25-30 pooris.
Roll And Half-Fry
Lightly brush your rolling board and pin with oil; never use dry flour, as it burns in the oil and sticks. Roll 4-5 balls into a 4–5-inch circle, slightly thicker than a regular poori. Even thickness is critical: thin edges fry faster and burn while the center is still cooking.
Pour enough oil into a deep kadai to reach at least 3 inches. Heat over medium-high heat to 180°C / 355°F.
Test it: drop a tiny piece of dough in; it should rise to the surface within 2 seconds. If it rises immediately, the oil is too hot. If it sinks and slowly rises, the oil is too cold.
Gently slide one poori into the oil. Wait 2–3 seconds, then press the surface lightly with a slotted spoon in a circular motion; this coaxes the poori to puff up.
Once puffed and golden on the bottom (about 4-5 seconds), flip and fry the other side for another 4-5 seconds. Drain on a paper towel. Repeat with the rolled poories.
Roll all the puris and half-fry them.
Double Fry The Bedmi
Once you are ready to serve, heat the oil until it is very hot. Then fry the half-fried puris from both sides until browned and crispy.
