This might not seem weird to many buy as a north american I had never encountered anything like it.
Shiso spice on rice.
It was a completely foreign flavor to me; like nothing I'd ever tasted before. Not a single thing in the north american diet is remotely close to what it tastes like. I saw there awestruck for a moment.
You can buy it online from Amazon wherever you're located. I got a bunch when I was going through a period experimenting with East Asian spices and condiments.
