One of my favorite sashimi is uni. At sushi restaurants, chefs open uni and serve the contents on the top of its shell. Delectable!
Super White Tuna was good when I tried it at a sushi restaurant. At another sushi restaurant, I was told that they do not serve it because humans cannot digest it. I was surprised to find that it was even banned in Japan.
Usually ginkgo nuts are sold at stores without their soft outer layer, so I was shocked from how stinky was the one fallen from a tree when I picked it up from the ground.
