<div class="method_step"><div class="method_num">1</div> Begin by marinating the beef brisket. In a mixing bowl, combine soy sauce, sesame oil, brown sugar, mirin, minced garlic, and grated ginger. Add the beef to the marinade, ensuring each piece is well-coated. Cover and let it sit in the refrigerator for at least 1 hour, or overnight for deeper flavor.</div> <div class="method_step"><div class="method_num">2</div> Once the beef is marinated, prepare the hot pot. In a large pot, heat olive oil over medium heat. Add the marinated beef, searing each side for about 2 minutes until lightly browned. Do this in batches to avoid overcrowding the pan.</div> <div class="method_step"><div class="method_num">3</div> After all the beef is seared, pour the beef broth and water into the pot. Bring to a boil, then reduce the heat to low, allowing the broth to simmer. This will form the base of your hot pot.</div> <div class="method_step"><div class="method_num">4</div> Add the sliced carrots, chopped Napa cabbage, and sliced mushrooms to the pot. Let the hot pot simmer for about 1 hour. This slow cooking process will infuse the broth with the flavors of the vegetables and make the beef tender.</div> <div class="method_step"><div class="method_num">5</div> Taste the broth periodically and adjust the seasoning with salt as needed. The key is to balance the flavors to your liking.</div> <div class="method_step"><div class="method_num">6</div> Just before serving, sprinkle the thinly sliced green onions on top of the hot pot for added flavor and color.</div> <div class="method_step"><div class="method_num">7</div> Serve the hot pot hot with a side of cooked rice.
