INGREDIENTS:

Komatsuna: Komatsuna, or Japanese mustard spinach, is the star ingredient in this dish. When selecting Komatsuna, opt for ones with vibrant green leaves and sturdy stems. The leaves should be free from blemishes, wilting, or yellowing, signaling freshness and optimal nutrition. The stems should be crisp to touch. The younger, tender Komatsuna leaves are preferable as they possess a milder flavor, perfect for this dish.

Komatsuna Substitute: If you can't find Komatsuna, other leafy greens such as spinach, swiss chard, napa cabbage, cabbage or mizuna can be used in its place. The flavor and texture may slightly vary, but the method will largely remain the same.

Aburaage: Aburaage is deep-fried tofu pouches. When selecting, the texture should be slightly spongy yet firm to the touch. It should have a light golden-brown color. If buying pre-packaged, ensure there's no excessive oil seeping. Freshness is essential, so always check the expiry date.

Aburaage Substitute: Thin slices of firm tofu, Atsuage, thick deep-fried tofu or satsumaage and deep-fried fish cake, can be an alternative to Aburaage.

Bonito Dashi: Bonito Dashi is a foundational Japanese stock made from dried bonito flakes. To ensure the highest quality, consider making it fresh at home using dried bonito flakes and kombu seaweed. However, if you're buying ready-made bonito dashi, look for authentic Japanese brands and ensure there aren't any unnecessary additives. A clear, amber-colored dashi indicates proper preparation. If in a hurry, dashi packets, similar to tea bags but filled with bonito and kombu, can be a quicker alternative – just steep in hot water.

Bonito Dashi Substitute: For those who prefer a different type of dashi, Kombu (kelp) or Shiitake mushroom dashi can be used as a replacement.

MAIN STEPS:

Komatsuna Integrity: While slicing the Komatsuna, retain uniformity in size. This ensures even cooking, preserving the vegetable's nutrients and texture. Overcooking them might result in a mushy texture, and you'll lose their natural vibrant green, which adds aesthetic appeal to the dish.

Aburaage Preparation: Aburaage, being tofu-based, absorbs flavors well. While slicing them, maintaining even strips ensures that they soak up the broth uniformly. Prepping them correctly can make the difference between a fully flavored bite and a bland one.

The Broth's Delicate Balance: When preparing the broth, heat it gently. Overheating can cause the alcohol in the Sake and Mirin to evaporate too quickly, altering the desired flavor profile. Slowly heating ensures the melding of flavors and prevents any one ingredient from overpowering the others.

Simmering Secrets: In step 06, simmering is vital. A gentle simmer, as opposed to a roaring boil, allows the Komatsuna and Aburaage to gradually absorb the flavors without compromising their structure. Monitor closely to avoid overcooking, aiming for the Komatsuna to be tender but not wilted.

Rest and Absorb: Post-cooking, letting the dish sit covered is essential. It's during this resting phase that the flavors truly meld, with the Komatsuna and Aburaage absorbing the savory broth further. This elevates the dish's depth and ensures that every bite is flavor-packed.

Serving Temperature: Serving at room temperature often allows the flavors to shine best. However, if you choose to reheat, do so gently to avoid overcooking the Komatsuna, preserving its crunch and the overall dish's integrity.

HISTORY:

Komatsuna, or Japanese mustard spinach, traces its origins to the East Asian region. The name Komatsuna is derived from the Komatsugawa district in Tokyo. Although it's called mustard spinach, it's more closely related to turnips. The vegetable is rich in calcium and has been cultivated in Japan for centuries.

Nibitashi is a traditional Japanese cooking method, where vegetables are blanched and then soaked in a seasoned broth. The aim is to impart deeper flavors to the ingredients while retaining their inherent freshness. This technique has been an integral part of Japanese cuisine, given the emphasis on appreciating the natural tastes of ingredients.

Komatsuna Nibitashi showcases the marriage of a native vegetable with a traditional cooking method. In historical texts, Komatsuna is often mentioned as a staple vegetable, particularly among commoners and farming communities. Its hardy nature, allowing it to grow during colder months, made it a reliable source of nutrition during times when fresh vegetables were scarce.

The use of Komatsuna in Nibitashi might have stemmed from the desire to preserve the leafy greens while adding flavors from the available seasonal ingredients. Over time, this dish became a comforting staple in many households, especially in the Kanto region.

With the advent of modern farming techniques and transportation, Komatsuna became available throughout Japan. The simple and nourishing Komatsuna Nibitashi grew in popularity across various regions, with each adding their twist based on local ingredients and palates.

Today, it's a dish that resonates with nostalgia for many Japanese, reminding them of home-cooked meals. Komatsuna Nibitashi can be found not only in households but also in traditional Japanese eateries, known as izakayas, and even in some upscale restaurants as a testament to its timeless appeal.

TIPS:

Blanching Technique: Before adding the Komatsuna to the broth, quickly blanch the segments in boiling water for about 30 seconds to a minute. This helps to retain the vibrant green color and removes any bitterness. After blanching, immediately plunge them into iced water to stop the cooking process.

Aburaage Preparation: To remove excess oil from Aburaage, quickly pour boiling water over it before cutting. This process will give the Aburaage a better texture and allow it to absorb the flavors of the broth more effectively.

Dashi Depth: If using instant bonito dashi, consider mixing it with a bit of kelp or kombu dashi for a more rounded and deep flavor. This combination will elevate the umami profile of the dish.

Katsuobushi Infusion: Katsuobushi (dried bonito flakes) has a deep umami flavor and a smoky aroma. Infusing your broth with it will deepen the taste profile, making it richer and more savory.
Method: After you’ve finished simmering the Komatsuna and Aburaage, sprinkle a generous handful of katsuobushi on top of the broth. Cover and let it steep for 2-3 minutes. Strain the liquid to remove the flakes before serving. This short steeping time is just enough to infuse the broth without overpowering it.

Sake Steaming: Fresh sake has a distinct aroma that can be lost when mixed and simmered with other ingredients. Using it as a finish preserves its aroma, offering a fresh, alcoholic fragrance that contrasts the depth of the simmered ingredients.
Method: Reserve about a quarter of your sake. When you're ready to serve, heat this sake in a saucepan until just before boiling. Pour it over the prepared Komatsuna Nibitashi, letting the steam carry the sake’s aroma to the diner's nose.

Notes:

Refrigerated Storage: Once cooked, you can store the Komatsuna Nibitashi in an airtight container in the fridge for up to 2-3 days. Reheat gently before serving if desired.

Cooking Ahead of Time: You can prepare the flavorful broth in advance. Once prepared, store it in the fridge and use it within 2-3 days. When ready to cook, just reheat the broth and proceed with the rest of the recipe steps.

Pressure Cooker/Instant Pot: You can use this appliance to speed up the simmering process. Use the sauté setting to warm up and blend the broth ingredients. Then, add Komatsuna and Aburaage, set it to 'low pressure' and cook for 1-2 minutes.

Vegetarian Alternative: To make this dish vegetarian, use a seaweed-based dashi like Kombu or a mushroom-based dashi like Shiitake instead of Bonito Dashi. Ensure that the Aburaage you use hasn't been fried in animal-derived oil.

Serving: Komatsuna Nibitashi pairs well with steamed rice as its mild broth complements the neutral taste of rice. You can also garnish with thinly sliced green onions or sesame seeds for added flavor and texture.
