In some areas and times, cockchafers were served as food. A 19th-century recipe from France for cockchafer soup reads: “roast one pound of cockchafers without wings and legs in sizzling butter, then cook them in a chicken soup, add some veal liver and serve with chives on a toast”. A German newspaper from Fulda from the 1920s tells of students eating sugar-coated cockchafers. Cockchafer larvae can also be fried or cooked over open flames, although they require some preparation by soaking in vinegar in order to purge them of soil in their digestive tracts.[14] A cockchafer stew is referred to in W. G. Sebald’s novel The Emigrants.
