In a bowl, add cornmeal and whole wheat flour. To this add oil. Give it a mix.
Next add in all the ingredients except yogurt and water to the flour mix. Give everything a mix with your hands.
Now add the yogurt, mix it in and start to knead the dough.
Next start kneading the dough by adding warm water as required
Once the dough is ready, cover it and let it rest for 15 to 20 mins
In a heavy bottom pot. Add Oil. Let it heat up. We are looking to heat up the oil between 375F to 400F. Once the oil is hot, we will start frying the vadas.
To make the vadas, on your rolling pin place a parchment paper, add 2-3 drops of oil and spread it on the parchment paper. Also, take water in a separate bow.
Now scoop 2 Tbsp's vada dough. Make a dough ball and place it on the parchment paper.
Now dip your fingers in the water and by using your fingers start tapping the dough, working your way from the center towards the edges in a round shape clockwise.
Once your vada is formed, dab some white sesame seeds on the top.
Now place the vada carefully in the hot oil and let it fry on medium high heat.
Fry it the way you fry puris and the vada should definitely puff up.
Continue making all the vadas in the same way. These taste amazing with hot cup of masala chai and gujarati keri no chundo, along with green chutney.
