The mikan is a small citrus fruit from Japan, also known as the satsuma orange. These pack a lot of flavor and are pretty good for you, and since they fall in the citrus family, most westerners will likely be warm to the idea of eating them. Sometimes you can find mikan in your local Japanese grocery store (or generic Asian grocery store), but you'll probably come across mikan-flavored candy instead. In one of my Japan Crates, I got a pack of Mikan Gummy, just ready to be devoured by me.
This candy absolutely delivered. These looked like oranges, and they tasted like oranges. They're really super cute too — and the packaging is bright and colorful. These were absolutely delicious, and I would happily buy them again.
