Into a mixing bowl, add all the chopped ingredients- onions, cashews, green chilies, fresh curry leaves, and grated ginger, along with white sesame seeds, poppy seeds, red chili powder, salt. If you are using dried curry leaves, crush and add them along. Mix all the ingredients well using your hand.
To this, add maida, rice flour, and upma rava. Mix everything well by squeezing the onions nicely so that their juice is released. After mixing well, the mixture will hold shape when pressed in your hand. If it does not, squeeze and mix more. Let this rest for 10 minutes.
In the meantime heat cooking oil in a wide pan such that it gets well heated, but make sure it does not get smoky. It should be heated on medium heat.
Once the oil is heated well, add 2 tablespoons of it to the mixture and give a quick mix. Divide this mixture equally into two bowls before adding water. This will ensure that the complete mixture will not get soggy over time.
Into the first bowl, add in 3 tablespoons of water and mix well to form a smooth dough. You need not have to knead, just mix well. If required, you can add a little more water.
Divide the dough into lemon sized balls, by applying oil to your palm if the dough is sticky.
Now there are 3 ways to shape the dough into vadas- you can either pat the dough on a butter paper, or press it in between your palms, or use a tortilla press. Just make sure to keep it slightly thick, say about 3-4mm.
Pat on a butter paper- apply oil to the butter paper and press a dough ball such it spreads and becomes uniformly thick. If it sticks to your palm, apply oil and press.
Press in between your palms- apply oil to both the palms, place the dough ball on one palm, and gently press using the other palm. Since rava gets stretchy, it is easy to press and stretch. I prefer this method.
Tortilla press- oil a butter paper, place the dough ball, cover it with another oiled butter paper and press it using a tortilla press. Remember to not press too thin.
You can press/pat about 3 to 4 dough balls at once depending on the size of your frying pan. Keep them all aside on the same butter paper or on a plate.
By now oil would be heated well, make sure to reduce the heat to low-medium before frying the vadas.
Carefully slide the shaped vadas into the oil. After a few minutes, flip and fry the other side. Continue to flip and fry well on both sides until both sides turn golden brown.
Once you have fried all the vadas from the first batch, add 3 tablespoons water to the mixture in the second bowl and proceed to make the dough and fry the vadas in the same manner.
Lastly, you can fry some curry leaves in the oil and add them to the fried vadas for a lovely flavor.
