its the season and what i think is actually little tunny (called bonito here) are passing through. weve filled up our freezer, but i would like to know a way to preserve the fish similar to canned tuna so that it is well preserved and ready to eat without preparation. for now ive been putting the bones and head into the oven, scraped off the meat and put it in a jar then covered with oil. tastes fine but is very oily even after draining it well. anyone know any better ways??
