Fried eggplant ice cream. I lived in Japan and taught elementary/junior high school, and once when I was teaching in a 5th-grade class, the teachers asked me to teach the students English words about taste, like salty/sweet/etc. while the students introduced the projects they had done on local, regional cuisine to me. I tried a lot of food items that day, but the worst was nasu-furai isu (fried eggplant ice cream.) Imagine the coolness and sweetness of ice cream cut with the texture of the oil, eggplant seeds, and crunchy bits I could not identify.
We got two barrels. Mostly it was people wanting to try it, but I do remember one woman who actually ended up ordering a scoop. The thing about this ice cream was that it made everything reek of garlic. The entire chest freezer we kept it in smelled of garlic after about 2 hours. We had that shit sitting around for Two. Fucking. Months. Two months of not wanting to open up the “vanilla” freezer because the store would smell of garlic. And then, when they finally told us we could throw it out…my boss did what we always did with ice cream that needed to be disposed of: set the open barrel in the slop sink and let it melt.
