Unagi Rice Bowl: A Taste of Summer Stamina

There are certain dishes that transport me back to a specific time and place with the very first bite. For me, unagi donburi is one of those profound culinary journeys. I can vividly recall standing in my mother’s small, bustling kitchen on a sweltering summer afternoon, the air thick with humidity and the tantalizing aroma of simmering sauce. My mother, a woman who believed deeply in the restorative power of good food, would meticulously prepare this dish, especially during the hottest months. She’d always say that unagi, with its rich flavor and satisfying texture, was the secret to keeping our energy up when the heat felt overwhelming. That memory, of the warm glow in the kitchen and the comforting weight of the rice bowl in my hands, is the essence of what unadon represents to me – a beacon of delicious, soul-nourishing tradition.

Instructions

The journey to a perfect unagi rice bowl begins with thoughtful preparation. If you are using frozen unagi, the first crucial step is to allow them to defrost thoroughly in the refrigerator. This process can take anywhere from 5 to 6 hours, so it’s best to plan ahead. While your unagi is gently thawing, you can turn your attention to the foundation of this dish: the rice.

Begin cooking the steamed Japanese-style rice according to your preferred method, whether that’s in a rice cooker or a pot on the stovetop. Ensure the rice is perfectly cooked – fluffy and slightly sticky, the ideal canvas for the rich flavors to come.

Next, it’s time to create the magical kabayaki sauce. In a small saucepan, combine the soy sauce, mirin (sweet rice wine), and sugar. Place the saucepan over medium heat and stir gently until the sugar is completely dissolved. Once dissolved, remove the sauce from the heat and set it aside. This rich, glossy sauce is the heart of the unagi’s signature flavor.

Now, let’s prepare the star of the show: the unagi. Heat the unagi following the instructions provided on its packaging. If, by chance, there are no specific instructions on the package, here’s a reliable method:

1. Place the defrosted unagi, skin side down, in a large skillet.
2. If the unagi pieces are long, you may need to cut them into halves lengthwise to better fit the skillet and ensure even heating.
3. Pour 1 tablespoon of sake rice wine evenly over the unagi pieces. This helps to tenderize the eel and add a subtle depth of flavor.
4. Cover the skillet with a lid.
5. Steam cook the unagi over low heat for a couple of minutes. This gentle cooking method warms the eel through without overcooking it, preserving its delicate texture.

Alternatively, for a quicker heating method:

1. Place the defrosted unagi on a microwave-safe plate.
2. Pour sake rice wine over the unagi.
3. Cover the plate with plastic wrap.
4. Microwave on high for about one minute, or until the unagi is heated through.

Once the unagi and rice are ready, it’s time for assembly. Serve the hot steamed rice into four large, individual rice bowls. Ladle a generous portion of the prepared kabayaki sauce over the rice. This will allow the rice to absorb some of that delicious glaze. Finally, top the sauced rice with the heated unagi pieces. For an extra burst of flavor, pour more kabayaki sauce over the unagi just before serving.

Expert Tips & Tricks

The beauty of using pre-cooked unagi is its convenience, but a little extra attention can elevate it further. When heating the unagi in the skillet, pay attention to the skin. You want it to be slightly crisp, not soggy. You can achieve this by ensuring the skillet is properly preheated before adding the unagi and by not overcrowding the pan. If your unagi package comes with extra sauce, don’t hesitate to incorporate that into your kabayaki sauce for an even more intense flavor profile. For a restaurant-quality presentation, you can garnish the unagi with toasted sesame seeds or finely chopped scallions.

Serving & Storage Suggestions

Unagi rice bowls are best enjoyed immediately after preparation, when the rice is warm and fluffy, and the unagi is perfectly heated. To serve, ensure each bowl has a generous portion of rice, a good amount of kabayaki sauce drizzled over it, and a few pieces of the glistening unagi on top.

Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. However, the texture of the unagi might change slightly upon refrigeration. To reheat, it’s best to gently warm the unagi in a skillet with a little extra kabayaki sauce or briefly in the microwave. Reheating the rice is also best done gently to avoid it becoming mushy.

Variations & Substitutions

While the classic unadon is exceptional, feel free to explore variations. For those who prefer a less sweet sauce, you can reduce the amount of sugar in the kabayaki sauce. If you’re looking for a gluten-free option, ensure you use tamari instead of soy sauce. For a spicier kick, a dash of sriracha or a pinch of togarashi (Japanese chili powder) can be added to the sauce. If mackerel is used as a substitute, adjust the cooking time as needed, as it may cook faster than unagi.

FAQs

Q: What is unagi-no-kabayaki?
A: Unagi-no-kabayaki refers to freshwater eel that has been butterflied, skewered, grilled, and coated in a sweet soy-based glaze called tare. It’s a staple in Japanese cuisine.

Q: Why is unagi considered good for summer in Japan?
A: In Japan, unagi is traditionally eaten during the summer months, particularly on “Doyo no Ushi no Hi” (the hottest day of summer), as it is believed to provide stamina and energy to combat the heat.

Q: Can I make the kabayaki sauce from scratch if I can’t find mirin?
A: While mirin is ideal for its unique sweetness and depth, you can substitute it with dry sherry or sake mixed with a little extra sugar to mimic its flavor profile.

Q: How do I know if the unagi is cooked through?
A: Pre-cooked unagi is typically already cooked. Heating is just to warm it up. It should be tender and heated through. If using a raw substitute like mackerel, ensure it is cooked until opaque and flakes easily with a fork.

Q: Is it possible to make unagi rice bowls gluten-free?
A: Yes, you can make this dish gluten-free by using tamari instead of regular soy sauce in the kabayaki sauce.
