Musaengchae (무생채) is a salad like dish that’s made with julienned radish. This recipe is a mild variation that’s simply seasoned with sugar, vinegar, and a little bit of salt.
Clean the radish and carrot by scrubbing with a brush and/or scratching off the stubborn impurities with a small knife. Cut into match sticks. You can use a mandoline if you have one.
Add all the remaining ingredients. Mix well by hand until the sugar is dissolved and the radish is evenly coated with the gochugaru (if using). Taste and add more vinegar or sugar to your liking.
