There is a female carp angler in sweden whoose name is Inger Nilsson. She wrote an article last year or the year before about alternative baits.
During her "test" she caught carp on raspberries, mushrooms, candy and some more interesting stuff.
She also happened to be my cooking-teacher a couple of years ago Her husband (or boyfriend, cant remember if they are married) is also a very good specimenhunter. His name is Kristian Nilsson.
