Korean Macaroni and Cheese with Beef, Kimchi, Cheddar - One stellar food pairing is kimchi plus cheddar. Funky tangy kimchi partners with sharp creamy cheddar, ground sirloin, and gochugaru, a Korean red chili powder that is definitely spicy – but also has a balanced fruitiness, slight smokiness and depth of flavor from the sun-dried red peppers. The resulting fusion dish is an irresistible grown-up full-flavored mac and cheese.
