First of all, rinse the Rice, Urad Dal and Methi Seeds (if using) thoroughly.
Soak all the ingredients in the required amount of water for 4-5 hours.
After that grind them using the wet blade of grinder jar. You can change the water before grinding. I would suggest using the same water in which the ingredients are soaked.
Keep aside the mixed batter in a bowl for about 8-9 hours at room temperature to enable the fermentation. I usually prefer to ferment the mixture overnight.
After 8 hours, check the rice batter if it is fermented properly or not. If it looks a bit thick, you can add 1/2 a cup of water to make the consistency perfect.
Meanwhile, chop the vegetables and take them in a mixing bowl.
Add some salt and turmeric as needed. Mix all the veggies nicely.
Now, take a pan. Heat some oil in it. Turn the flame to low.
Pour gently the batter using a ladle or spoon into the pan.
Now after 30-40 seconds, spread some veggies on top of the uttapam.
Sprinkle some oil over the batter and veggies. This will look like a thick pancake.
Flip the uttapam. Cover the pan with a lid and let it cook on low flame for about a minute.
After 1 min, uncover the pan. Flip the other side and cook for few more seconds if required.
Cook both sides properly. Keep patience and follow these steps to prepare Uttapam for the rest of the batter.
Your Uttapam is ready. Serve it hot with some coconut chutney or sambar dal. You can enjoy it even with some tomato ketchup as well. :)
