Shabu Shabu Thinly Sliced Beef Hot Pot

Gently wipe the kombu with a damp cloth, do not rinse. Place the kombu in a large pot or donabe (hot pot) with 8 cups of water. Let it soak for at least 30 minutes, or ideally 2-3 hours in the refrigerator. Slowly heat the pot over medium-low heat. Just before the water comes to a boil (when small bubbles appear), remove the kombu. Do not boil the kombu, as it can make the broth bitter.

While the kombu soaks, prepare all your vegetables. Roughly chop the napa cabbage. Remove stems from shiitake mushrooms and score the tops if desired for aesthetics and flavor infusion. Trim the root ends from enoki mushrooms and separate them into smaller clusters. Cut firm tofu into 1-inch cubes. Peel and thinly slice carrots, or use a cookie cutter for decorative shapes. Cut scallions into 2-inch pieces.

Artfully arrange the thinly sliced beef, prepared vegetables, and tofu on separate platters. This makes it easy for everyone to pick and choose their ingredients during the meal. Prepare your dipping sauces (ponzu and goma dare) in small individual bowls at each place setting.

Place the pot with the dashi broth on a portable induction burner or gas stove in the center of your dining table. Bring the dashi broth to a gentle simmer over medium heat. Keep the heat at a level where the broth is simmering gently, not aggressively boiling.

Each diner can now begin cooking. Using chopsticks, pick up a slice of beef and swirl it in the simmering broth for just a few seconds until it changes color and is cooked to your preference (it should still be slightly pink for maximum tenderness). Dip the cooked beef into your chosen sauce and enjoy. Next, add vegetables and tofu to the pot. Harder vegetables like carrots and napa cabbage stems go in first, followed by mushrooms and softer cabbage leaves.

Continue to cook and enjoy the ingredients at your own pace. The broth will become richer in flavor as more ingredients cook in it. Replenish ingredients in the pot as needed. Ensure the broth remains at a gentle simmer throughout the meal, adjusting the heat as necessary.

Towards the end of the meal, once most of the solid ingredients are consumed, you can add udon or ramen noodles to the flavorful broth. Cook them until tender. Alternatively, you can make a zosui (rice porridge) by adding cooked rice and a beaten egg to the remaining broth, simmering until thickened and garnishing with scallions.
