What you get
Open a convenience store fridge in Korea and my hand goes to this shelf on autopilot. Binggrae Banana Flavored Milk, ₩1,800 for the 240ml bottle at CU — the shelf tag said exactly that. I grabbed two. Should’ve grabbed three, but we’ll get to that. The bottle is half the product, honestly. That chubby jar shape is where the nickname comes from: ttungba, roughly ‘chubby banana milk.’ And the ritual matters: you don’t peel the foil lid. You stab a straw straight through it. That little pop is part of the flavor, I’m convinced. Here’s the thing visitors should know: this is bathhouse milk. You come out of a scalding-hot mokyoktang (public bathhouse) or a jjimjilbang, skin steaming, hair dripping, and you down one of these ice cold in basically one pull. Nobody teaches you this. It’s just what you do, and it’s been what you do for generations — right up there with the roasted eggs and sikhye at the sauna. If you’re doing a jjimjilbang on your trip, the banana milk after is not optional. Taste-wise? It’s candy-banana, not actual-fruit banana, and that’s precisely the point. Sweet, milky, cold, gone in about forty seconds. There’s a strawberry version and a coffee version in the same jar. They’re fine. They are not this.
