This summer stamina unagi donburi bento by a soon-to-be-bride is a medium-difficulty dish that can be completed within 40 minutes using prepared unagi and pre-cooked rice.

Filled with sincerity, it makes a wonderful gift.

🛒 Ingredient Tips

Freshness is paramount for unagi.

When purchasing prepared seasoned unagi, always check the manufacturing date and choose pieces that are firm and glossy.

For frozen unagi, check if it's plump and has minimal moisture after thawing.

For eggs, fresher ones have a firm yolk and elastic whites.

For egg ribbons, letting eggs come to room temperature beforehand can result in smoother ribbons.

It's best to choose perilla leaves (kkaennip) that are vibrant green, fragrant, and not wilted.

The aromatic quality of perilla leaves will further enhance the flavor of the unagi.

🔄 Substitution Guide

If you wish to use other ingredients instead of unagi, you can thinly slice chicken breast or beef sirloin and simmer them in soy sauce to enjoy as a donburi.

While it won't have the unique flavor of unagi, it's a good alternative for protein.

You can also use sugar or oligo syrup instead of allulose.

Sugar is sweeter than allulose, so reduce the amount by about half.

If you don't have perilla leaves (kkaennip) or dislike them, you can substitute with mild leafy greens or finely chopped chives.

If wasabi (gochunaengi) is too strong, a light drizzle of mayonnaise can add a touch of creaminess.

👨‍🍳 Cooking Points

There are three key points to this recipe.

First, when simmering the onion sauce, it's important to stir constantly over medium heat to prevent burning and allow the onions to deeply absorb the flavor. Avoid high heat.

Second, when making egg ribbons, lightly drizzle cooking oil in the pan, spread it thinly with a paper towel, then pour a thin layer of egg mixture over low heat to create smooth ribbons without holes.

Straining the egg mixture through a sieve once will result in an even smoother finish.

Third, warm the seasoned unagi over medium-low heat for only 2-3 minutes.

Pay close attention to the heat to prevent the seasoning from burning, which can lead to a bitter taste, ensuring delicious unagi.

👨‍🍳 Directions

1

Before cooking, wash your hands thoroughly and begin preparing the vegetables.

2

Thinly slice half an onion crosswise for the sauce.

3

Snip the scallions (jjokpa) into small pieces with scissors for garnish.

4

Remove the stems from the perilla leaves (kkaennip), roll several leaves together, and snip them into small pieces with scissors to serve with the unagi.

5

Make the unagi donburi sauce. Mix 2 tbsp soy sauce, 1 tbsp mirin (mat-sul), and 1 tbsp allulose.

6

Whisk 3 eggs to prepare the egg mixture for egg ribbons.

7

Lightly drizzle cooking oil in a pan, sauté the onions until translucent, then add the prepared sauce and simmer until the sauce is well absorbed by the onions.

8

Lightly drizzle cooking oil in another pan, spread it evenly with a paper towel, then pour a thin layer of the egg mixture over low heat to make egg ribbons. If holes form, add a little more egg mixture to fill them.

9

Roll up the cooked egg ribbons and thinly slice them into bite-sized pieces.

10

Lightly drizzle cooking oil in a pan and warm the seasoned unagi over medium-low heat for 2-3 minutes.

11

Heat the pre-cooked rice, then spread it evenly in a wooden bento box.

12

Sprinkle a pinch of furikake over the rice.

13

Arrange the thinly sliced egg ribbons attractively over the rice.

14

Place the sliced perilla leaves (kkaennip) on top of the egg ribbons.

15

Spoon the simmered onion sauce over the perilla leaves (kkaennip).

16

Cut the warmed unagi into bite-sized pieces with scissors and place them over the rice.

17

Garnish the unagi with snipped scallions (jjokpa) and wasabi (gochunaengi) to complete the unagi donburi bento.

18

Cut the apple in half, then thinly slice it (for a pleasant eating experience) and place it in a fruit bento box.

19

Cut the mandarin orange in half and place it in the fruit bento box with the apple.

20

Sprinkle snipped scallions (jjokpa) over the fruit bento for decoration to complete the fruit bento.

💡 Tips

Slicing onions crosswise yields a crisp texture, while slicing them lengthwise results in a softer texture.

When making egg ribbons, straining the egg mixture through a sieve once can result in smoother ribbons.

When warming seasoned unagi, it's best to heat it over medium-low heat for only 2-3 minutes, as the seasoning can burn and create a bitter taste.

Slicing apples thinly makes them easier and more pleasant to eat.

📦 Storage & Reuse

The finished unagi donburi bento is best eaten immediately, but if refrigerated, store it in an airtight container and consume within 1 day.

As unagi is a perishable ingredient, it's recommended to eat it as soon as possible.

To reheat, microwave for 1-2 minutes covered with plastic wrap, or gently warm it in a pan over low heat.

Leftover onion sauce can be used in other donburi or bibimbap dishes, and leftover egg ribbons can be finely chopped and added as a garnish to soups or stews for beautiful color and soft texture.
