Take bajra flour, atta, ginger, garlic, green chilies, red chili powder, turmeric powder, coriander-cumin powder, sugar, salt, sesame seeds, and oil in a big mixing bowl. Mix well.
Make some space (hole) in the center of the mixture and add baking soda and yogurt. Mix both very well.
Now mix everything well. Add water and start kneading the dough.
Make a very soft (softer than roti dough) and smooth dough.
Lay a clean plastic sheet or damp cotton cloth on a worktop. Apply some oil on a plastic sheet.
Take a marble-sized ball from the dough and place it on the plastic sheet, cover it with one more plastic sheet, press using a flat bottom bowl (check video), and make a not-too-thick or thin 2″ diameter round disk.
Sprinkle some sesame seeds and gently press them with your fingers so they stick to the disc.
When you finish shaping the vada, heat the oil on medium heat for frying. Oil should be medium hot.
Once hot, slide a few bajri vadas into the hot oil and fry. Don’t overcrowd the pan; fry a few at a time.
Once puffed up, flip them and fry until golden from all sides.
Remove them to the paper towel-lined plate using a slotted spatula when they are crispy and golden brown from both sides.
Repeat with the remaining dough.
Enjoy Bajri Na Vada with tea and chutney.
