Eating Fish Parts
Many moons ago, there was the huge World Famous Red Snapper Fleet at Pensacola Florida.
You could go down to the cleaning docks and buy a complete snapper head for a dime(yes; 10 cents).
The whole thing, after washing cleaning out the gills and eyeballs, would go into a big stock pot on the back of the stove and boiled, along with different mixtures of spices, releasing all of the edible parts from the skull..
Thia would make into some of the best tasting chowder, gumbo and other concoctions that would feed a whole household pretty well.
I fillet a whole Redfish from stem to stern, remove the gills, eyeballs and guts then bake it. There's a lot of meat there; some of which is 'normally' wasted.
Try it; you might like it. JMHO C2
