Some philipino folks around here are catching redfish from their kayaks and makinig fish head soup from it. Sounds amazing. I was a bit intimidated. i want to see them make it once.If you live somewhere warm and get access to fresh fish, I think fish broth is an excellent option since the tropical fish are low in fat. Also, fish broth is very quick, 25-30 minutes of boiling is enough to produce a very thick gelatinous broth, which in combination with some vegetables makes for some very good eating. If you put the head in too you might get some thyroid as well.
