Few handfulls of salt after you place them in clean water a few times till muddiness does not show. If camping alongside Riverbed where you caught them it pays to carry with you a swag of old Newspapers you no longer have use for.
After your carp comes up clean from the above , fill the gut cavity with celery , onion , carrot along with some butter.
Wrap the carp whole in plenty of Newspaper , throw the bundle in in the ashes of your campfire , cover with ash and let cook for at least an hour.
Pull newspaper wrapping from ashes and as you unfold all the scales should come away stuck to the newspaper.
You will have to put up with sorting through the bones in this cookup but not that bad a dish for in the Sticks if your rabbit traps came up empty , and fills the void..
