The most delicious thing I ever ate was 2 years ago in Korea when I was served on two occasions
Matsutake mushrooms which are apparently the most expensive mushrooms in the world. They were freshly picked from the property of a relative that morning and sliced raw on a plate. The aroma that rose from that plate was.. astonishing. Intense and foresty and alive. I was in awe. I have never smelled anything like it. I was urged to dip them in sesame oil and other things but I did not, I wanted to savor them just as they were. I had to stop myself from eating too much and when I got served them a second time a few days later I was just so happy.
It's an unrepeatable experience, unlike amazing dishes I can't go home and try and replicate it myself. I could buy them imported most likely but I know they will not be the same as ones that were still in the ground a few hours before.
