Shabu Shabu Thinly Sliced Beef Hot Pot

In a large pot or donabe (hot pot), combine 8 cups of water and the kombu. Let it sit for at least 30 minutes, or ideally, overnight in the refrigerator for maximum flavor extraction. Slowly heat the pot over medium-low heat. Just before the water comes to a boil, remove the kombu. Do not boil the kombu as it can make the broth bitter. Keep the broth simmering gently.

While the dashi is preparing, wash and prepare all your vegetables. Cut the napa cabbage into bite-sized pieces. Trim the stems from shiitake mushrooms and score the caps if desired. Trim the root end of enoki mushrooms and separate them into smaller clumps. Peel and thinly slice the carrot, or use a cookie cutter for decorative shapes. Cut the tofu into 1-inch cubes. Arrange all prepared vegetables and tofu aesthetically on a large platter.

Carefully separate the very thinly sliced beef and arrange it neatly on a separate platter. Ensure the slices are easy to pick up individually. Keep the beef refrigerated until just before serving to maintain its freshness.

Place the hot pot (donabe or electric hot pot) with the simmering dashi broth in the center of your dining table. Arrange the platters of beef, vegetables, and tofu around the hot pot. Provide individual dipping bowls for each diner, along with small plates for cooked ingredients and serving utensils like chopsticks or small tongs.

Once the broth is simmering gently, diners can begin cooking. Each person picks up a slice of beef with their chopsticks and gently swishes it in the hot broth for a few seconds until it changes color and is cooked to their preference (usually still slightly pink). Dip the cooked beef into your choice of ponzu or goma dare sauce. Then, add vegetables and tofu to the broth to cook until tender, also dipping them in sauce before eating.

Continue cooking and enjoying the beef and vegetables, replenishing the hot pot as needed. Towards the end of the meal, after most ingredients have been cooked, the broth will be rich with flavor. If desired, you can add cooked rice to the remaining broth, simmer until it becomes a porridge-like consistency (zosui), and serve as a comforting finish to the meal.
