Korean cuisine is famous for its unique flavour profiles, mixing earthy layers of spicy, sweet, fermented and savoury. Its most popular export, Korean barbecue, is a perfect example of how these essences work together. While many diners around the world know that it involves making a ssam (spicy meat, picked vegetables and rice bundled inside a cool, crispy lettuce leaf) this familiar pairing is just one of countless unspoken rules when it comes to eating Korean food.
