yes. it’s good to soak and blend them separately. soak rice in a bowl of water. in another bowl, soak urad dal and methi seeds. while grinding, grind the urad dal and methi together adding water. after transferring them, grind the rice with poha adding water. transfer it to the same urad dal batter bowl and mix well. they are soaked for about 2 to 4 hours in enough water.
