I had two delicacies from some rural Japanese prefecture courtesy of my students.
One was bee larvae marinated in a soy sauce base of some sort and the other was crickets also marinated in that sauce. All I could taste was the sauce, really, although the crickets were crunchy.
The WORST thing I've ever had was sült (or headcheese) when I was in Estonia. If it's true that laws are like sausages and that it's better not to see them being made, then that goes double for sült. I saw and smelled it being made. I'd go back to Korea and eat bosintang before eating sült ever again.
Now blood sausages on the other hand, were yummy.
