This is a Japanese interpretation of Korean Beef Soup with Rice. Just the right amount of chilli from gochujang (Korean red chilli paste) and Kimchi makes this rice soup slightly spicy and sour. Prep Time includes time to marinate the beef strips as I assume that you prepare other ingredients while the beef is marinating.Don't forget to see the section 'MEAL IDEAS' below the recipe card! It gives you a list of dishes that I have already posted and this recipe that can make up a complete meal. I hope it is of help to you.
