These are my father-in-law's favorite mushrooms called Matsutake mushroom.
Last autumn, he invested as much as 18,000 yen on some matsutake mushrooms.
He cooked sukiyaki with them and ate all of them by himself!
Before that, I knew he wanted to get sukiyaki beef, so I bought some high-end sukiyaki beef which cost about 10,000 yen.
I expected he would give me some when he cooked it. I couldn't believe how he could eat all of them and was surprised to know he was so greedy!
The next day, he complained of his bad physical condition. That's just his desserts.
