Tried one today alongside a white bass, small channel cat, and crappie. The drum was the worst of the mess but far from terrible. They were all fried the same way , the drum just had a more mushy texture. That surprised me because the filet was firm and the cleanest white color of the bunch. Overall, if it served by itself rather than with superior species, I'd never think I was eating drum.
Note, all were under a pound when caught and all but the crappie were caught in the Mississippi River on Tuesday. Also, the ranking for me was crappie #1, then white bass, baby channel cat, then drum.
