You should buy something similar to : add w3 .snackpellet.com/pl/snack/proces_smazenia/
You should fry it in oil in 180 degrees, to the moment of come to the top of light yellow snacks.
You can check the temperature by throwing couple of snacks to the boiling oil and when they grow up in few seconds you can throw to the oil some more of them.
Don't throw too many snacks at once.
Sorry for my english:)
