Take 2 cups water in a wide vessel . Add salt . Keep on stove and bring to boil.
When the water starts boiling , add rava slowly.Keep stirring so that no lumps are formed. Let it thicken to upma consistency. This may take 1-2 mins after adding rava. Switch off.
Then to it add rice flour, butter, jeera,til,hing and chilli powder. Knead into a dough.If required sprinkle little warm water.Knead it into medium soft dough, neither stiff nor loose.
Now heat the oil in a kadai / pan.
While the oil is getting hot, grease the chakli mould and fix the chakli plate to chakli mould . Divide the dough into parts . Add one part of the dough to the mould & press .

Press the dough into spirals of Chakkuli on a wax paper or greased plastic sheets
Once the correct temperature is reached, gently holding the end of the foil in one hand, slowly remove the flattened discs and drop them into the hot oil in batches of 4-5 depending on the size of the kadai used to deep fry.Deep fry them on medium low flame on both sides till they turn crisp and golden brown both sides.Once done, remove from oil and transfer to a paper towel.
Repeat the same for the remaining dough.
Store the Chakkuli / Chakli / Murukku in air tight containers once cooled. Remains fresh for minimum 1 month.
If the chaklis are drinking oil ---> addition of butter to the dough is more,or flame is too low. then either alter the flame or add some more rice flour.
If they are breaking while making spiral rounds ---> addition of butter to the dough is more.
If the chaklis are becoming soft ---> they are not properly cooked .
Check the oil readiness by dropping a small ball of dough into the oil. It has to come up immediately. This shows that oil has attained the right temperature n you can gently slide the chakli.
While dropping the prepared chaklis, the flame should be high,once they float to to top,reduce the flame to medium or medium low flame and fry till they become crisp.
Do not press all the chakli at one go. Make it in batches. Else they will dry .While the chakli is getting fried in oil, press the next batch of chakli.
