You just fillet them (don't scale, just cut off the skin) like any other fish! Cut out the rib-bones and what's left is white, firm meat. When I fried up remora, speckled trout and spanish mackerel for friends, they liked the remora best and speckled trout second. Spanish was still "good", they said, but a little fishier-tasting than the other two. No aftertaste on the remora. They don't yield as much meat as most other fish, but still very worth it on those large ones that hang around the pier feeding on baitfish that I cast off my hook.
