First boil the potatoes. keep it in the fridge for a couple hours and let them cool. Then peel their skin off.

Now grate the potatoes, using grater. Also boil the corn kernel until they are soft. Once soft let them cool on room temperature.

Take a big bowl and add the grated potatoes, corn kernel, chopped green chilli, salt, red chilli powder, u aamchoor powder and suji. And mix them well using your hands. After mixing well keep the mixture on the side for 10 minutes.

In the mean time let the tawa heat up. Once heated, grease it with ghee/oil. The amount ghee/oil depends on the use of tawa you are using. I used non-stick tawa so I only used a spoon of ghee/oil but in case of normal iron tawa, you need to use a lot more than 1 spoon of ghee/oil.

Now take a good portion of the mixture in your hand and make a ball of it and put it on the hot tawa and flatten it, using your fingers. Do the same with the rest of mixtures.

Cook the tikki from both sides, until they turn golden brown. And serve it with green chutney.
