Heat up enough oil in a deep pan . To check the temperature , drop one flake in the oil , if it pops up and expands within 30 seconds , the temperature is perfect.
Fry the maize flakes in small batches , stirring with a perforated ladle till they expand , become golden and crisp. Shake off the excess oil and place the fried flakes on absorbent kitchen paper.
In the same oil , fry the peanuts , curry leaves and raisins, one after the other. Drain on kitchen paper.
Transfer the fried maize flakes, curry leaves, peanuts and raisins in a mixing bowl. Sprinkle powdered sugar , salt , turmeric powder and red chilly powder over it. Toss the chivda , so that the flakes are evenly coated with all the spices but still retain their shape.
Taste the chivda and adjust the seasoning. Let it cool and then transfer it to an air tight container.
