If you have bought roasted peanuts from the market then peel of their skin. If you want to roast peanuts at home, then mix one small spoon of water in them, after 2 to 3 minutes roast them in a microwave for 4 to 5 minutes. If they are not properly roasted, then roast them for another 2 minutes. Peel off the skin after they have cooled.
Put small spoon of ghee in the frying pan and heat it. Then break the jaggery and put it in the frying pan and keep stirring with a frying spoon (on medium flame). The jaggery starts melting. Do not stop stirring. After 6-7 minutes take out one drop of syrup on a plate, if it starts freezing, then the syrup is ready. If it doesn't freeze then cook for another 2-3 minutes and test. The syrup is ready now.
Mix the peanuts in the syrup and cook for 2 to 3 minutes, while stirring vigorously. Put the ghee on a plate to make it oily. Now take out the ready syrup or chikki from the frying pan and quickly spread it on the oily plate. Cut it into your preferred size with a knife. After they have cooled separate the pieces.
The amazingly delicious Peanuts Chikki is ready now. Store it in an air tight container, so that you can have the chikki, whenever you feel like it.
