Edo Loach Hot Pot (柳川鍋, Yanagawa Nabe)

Ingredients

Equipment Needed

• •Shallow donabe (clay pot), or a wide flameproof skillet
• •Wooden drop-lid (otoshibuta), or a circle of parchment with a small center hole
• •Fine-mesh strainer lined with a clean cloth
• •Small tori-zara plates for serving

Instructions

1. 1

   Make the dashi

   Wipe the konbu with a damp cloth, but don't wash it. Put it in 4 cups cold water and bring it slowly to just under a boil over low heat, about 10 minutes. When the water trembles and small bubbles climb the sides, lift out the konbu. Add the katsuobushi all at once, take the pot off the heat, and leave it alone for 2 minutes while the flakes sink. Strain through a cloth and let it drip on its own.

   Boiled konbu turns the stock faintly bitter, and squeezed bonito flakes press strong oily flavors into it. The rule is simple because the thing you're guarding is simple: clarity.
2. 2

   Shave the burdock

   Scrub the gobō well, leaving the fragrant outer skin in place. Shave it into sasagaki by cutting thin diagonal shavings while turning the root a little after each cut, like sharpening a pencil. Drop the shavings into water for 5 minutes, swish once, then drain well. The brief soak lifts grit and harshness; a long soak washes away the earthiness that belongs in this pot.

3. 3

   Prepare the loach

   Keep the cleaned, split dojō cold until the pot is ready. Rinse only if needed, then pat dry and lay the pieces flat. If you are starting with whole loach, ask the fishmonger to purge, gut, and split it for you. This is sourcing work, not a test of courage. The fish should smell clean, more fresh water than mud.

4. 4

   Season the broth

   Measure 2 cups of the fresh dashi into a shallow donabe or wide pan. Add the shōyu, mirin, sake, and sugar, then bring it to a quiet simmer. Taste it before anything goes in. It should be a little stronger than soup, because the burdock, fish, and egg will soften the seasoning. This sweet soy simmering broth is warishita.

5. 5

   Cook the burdock

   Spread the drained gobō in a loose, even bed across the simmering broth. Set a wooden drop-lid, otoshibuta, directly on the surface, or use a circle of parchment with a small hole in the center. Simmer for 3 to 4 minutes, just until the shavings bend. The lid keeps the burdock down in the broth, so it seasons evenly without stirring.

6. 6

   Add the loach

   Remove the drop-lid and lay the split dojō over the burdock in one layer, flesh side up. Spoon a little broth over the fish, cover the pot, and simmer gently for 5 to 7 minutes, until the flesh turns opaque and the pieces relax. Don't stir. The burdock is the bed, not something to toss, and stirring breaks the fish and clouds the broth.

7. 7

   Bind with egg

   Beat the eggs lightly with chopsticks, just until the whites and yolks are loosened but not foamy. Pour two-thirds of the egg around the pot and over the fish. Cover for about 40 seconds, until the edges are barely set, then scatter the mitsuba and pour in the remaining egg. Turn off the heat, cover, and let the pot stand for 1 minute. Residual heat finishes the egg softly; hard boiling makes it grainy and hides the fish you worked to keep clean.

8. 8

   Finish and serve

   Dust lightly with sanshō and bring the donabe to the table with small tori-zara plates. Serve with hot rice and spoon a little broth into each portion. Eat while the egg is still tender and glossy, because the pot keeps cooking in its own warmth even after the fire is gone.

Chef Tips

• •Buy dojō from a fishmonger or aquaculture source and cook it the day you bring it home. Don't use wild-caught loach from untested water. The old Edo pot was a market dish, not permission to trust any ditch.
• •Ask for the loach cleaned and split, hiraki, for Yanagawa nabe. Whole loach belongs to a different Edo pot, dojō nabe. The distinction is small on paper and large in the bowl.
• •Shave the gobō thin enough that it bends in the broth but still has bite. Thick pieces stay woody, and soaked-to-death pieces lose the clean earthiness that makes this pairing work.
• •Don't reach for instant dashi here. The broth is not background; it is the field that carries fish, burdock, soy, and egg. Powder makes the pot salty before it makes it deep.
• •A burdock and egg pot made with eel, beef, or tofu can be good, but it is yanagawa-style, not Yanagawa nabe. That distinction keeps the name honest.

Advance Preparation

• •The dashi can be made up to 2 days ahead and refrigerated. Warm it gently before mixing the warishita.
• •The warishita can be mixed a day ahead once the dashi is made. Keep it chilled, then bring it to a simmer before adding the burdock.
• •Shave the gobō shortly before cooking. If you must do it ahead, hold it in water no longer than 30 minutes, then drain well so you don't wash away its character.
• •Buy the dojō the day you cook it. Keep it covered and cold, and do not let it sit in the refrigerator overnight if you can help it.
