Heat 1 cup water with required salt in a pan and let it boil on high flame. Once the water comes to a boil, keeping the flame on medium start, add rava slowly, stirring continuously with the other hand.
This helps to prevent any lumps formation and rava absorbs water.
Let it cook until it turns thick and dense in consistency.
Cover and simmer on low flame for 2 minutes or till rava is cooked well.
After this turn off the flame and keep covered for 2 to 3 minutes. The semolina will puff up.
Meanwhile, take a bowl and mash the boiled potatoes. Make sure there are no lumps.
Now add the puffed semolina, green chilies, coriander leaves, red chilly powder, turmeric powder and salt
Mix well so all ingredients infuse well together. Ready the mixture into a dough.
To make crispy fingers, grease your hand with oil. Lift a small lump from the dough. First, bind it a bit. Make a cylindrical shape to a finger length. Prepare all the fingers like this. Add oil in a pan and heat. Check if the oil is medium hot. Put the finger to fry.
Keep the flame medium. Make sure you put them to fry one by one.Stir occasionally and fry till the potato fingers turn crispy and golden brown.
Steaming hot and crispy potato finger is ready to be relished. Relish the snacks during the evenings. It can be served as a starter at any party.
