This recipe is from the blog, Maangchi. They write "This spicy grilled squid is a favorite in Korean bars, and if you’ve ever been to one, you couldn’t have missed it. A huge grilled squid covered in shiny, juicy, spicy sauce in the middle of a table full of drinkers. It’s not a dish you eat alone, you share it with friends, the more the merrier, usually with makgeolli or soju. But it’s not just for bars and booze! If you and your family like squid and spicy food, it makes for a great side dish with rice at dinner. But whether it’s in a bar or at home, it’s best presented to the table still sizzling, and then cutting the rings with scissors just before eating. Watching that performance will stimulate anyone’s appetite!"
