Microwave raw cornflakes in batches on high power (800W) for 1 minute to 1 minute 10 seconds. Time varies based on the microwave wattage. For one batch, spread 3/4 cup of cornflakes evenly on the turntable or a microwave-safe plate. Keep an eye so it does not get burnt.
Remove and repeat the same for all batches. Transfer to a wide bowl and let cool down.
Next, microwave thin poha for a minute and check whether it becomes crispy. If not, microwave for another 30 seconds to a minute. Remove and add to the cornflakes.
Then add dalia (roasted gram dal) and microwave for 1 minute 30 seconds. Remove and mix into the bowl.
Spread the raw peanuts and microwave for 2 to 2 1/2 minutes. Remove and keep in a separate plate. Peanuts may taste slightly soft initially, but they turn super crunchy once completely cooled. Once cooled and crispy, add them to the cornflakes mixture.
Next, microwave cashews for a minute until lightly golden and remove. Add to the bowl.
Microwave curry leaves for a minute until crisp. Remove and add them to the bowl.
Mix everything gently with required salt and set aside.
In a small kadai or tadka pan, heat oil and add raisins. Roast for a minute until raisins puff up. Add red chilli powder, turmeric powder, chaat masala and sugar. Turn off the flame immediately and pour this spiced tempering over the mixture. Mix everything together thoroughly until evenly coated.
Check for taste and adjust seasoning if needed. Allow the chivda to cool completely, then store in an airtight container. Stays crispy for more than a week!
