Dashi-Steeped Spinach (ほうれん草のお浸し, Hōrensō no Ohitashi)

Dashi-Steeped Spinach (ほうれん草のお浸し, Hōrensō no Ohitashi)

Created by

Ohitashi is quiet food: spinach blanched, cooled, squeezed dry, then steeped in dashi and light soy until the greens taste clean, deep, and plainly themselves.

Spinach has a small window when it tastes truly sweet: cold-weather leaves, dark green and firm, with stems that snap instead of bending. That is the spinach you want here. Hōrensō no ohitashi looks almost too plain to matter, which is exactly why it matters. There is nothing heavy to cover a tired leaf.

Ohitashi means something steeped. The cooking is quick, but the resting is the dish. You blanch the spinach to soften its fibers and fix the color, chill it to stop the heat, then squeeze it dry before it meets the seasoned dashi. That squeeze is the point. Leave water in the greens and the broth turns thin, as if someone whispered the seasoning from the next room.

This is the kind of small dish that sits beside rice, soup, and a grilled or simmered dish, one clear green note in the meal. Cut the bundle cleanly, lay it in the bowl with a little height, spoon over just enough broth to glisten, and leave it room. The real thing is not difficult. It only asks you to respect the spinach.

Ohitashi belongs to a broad family of Japanese aemono and kobachi, small dressed or steeped side dishes that appear in everyday meals and formal kaiseki alike. The word comes from hitasu, meaning to soak or steep, and older preparations used seasonal greens such as komatsuna, nanohana, and spinach as they became common on the table. Spinach reached Japan through foreign trade in the early modern period and was well established as a winter green by the Edo period.

The technique, the tradition, and the story behind every dish.

Ingredients

fresh spinach

Quantity

300g

washed well, roots trimmed only if tough

dashi

Quantity

1 cup

chilled or at room temperature

usukuchi shōyu (light soy sauce)

Quantity

1 tablespoon

mirin

Quantity

1 teaspoon

sea salt

Quantity

1/4 teaspoon

for the blanching water

katsuobushi (bonito flakes) (optional)

Quantity

1 tablespoon

Equipment Needed

  • Wide pot
  • Bowl of cold water
  • Shallow dish for steeping
  • Small Japanese side bowls

Instructions

  1. 1

    Wash the spinach

    Wash the spinach in several changes of cold water, especially where the stems meet. Sand hides there. Keep the stems attached if they are tender, because they give sweetness and a pleasant bite. Trim only the dry ends.

  2. 2

    Mix the dashi

    Stir together the dashi, usukuchi shōyu, and mirin in a shallow dish. Taste it before the spinach goes in. It should be clear, lightly salty, and a little round from the mirin, because the greens will soften the seasoning as they steep.

    Use real dashi here. The broth is not a background flavor in ohitashi, it is the thing the spinach drinks.
  3. 3

    Blanch stems first

    Bring a wide pot of water to a boil and add the salt. Hold each spinach bunch by the leaves and lower the stems into the water for 20 seconds, then lay the leaves in for another 20 to 30 seconds. The stems need a small head start so the whole bunch finishes at once, tender but still bright green.

  4. 4

    Chill and squeeze

    Lift the spinach into a bowl of cold water. Swish it gently, then drain and line the stems together. Squeeze from the stem end toward the leaves until the bundle feels damp but no longer drips. Be firm, not brutal. If water remains, it will dilute the dashi and the whole dish will taste tired.

    This squeeze decides the dish. Dry greens can drink seasoned dashi; wet greens only make weak broth.
  5. 5

    Cut and steep

    Cut the spinach into 2-inch lengths, keeping the stems and leaves roughly aligned. Lay the pieces in the seasoned dashi and turn them once so every cut face meets the broth. Let them steep 10 minutes, or up to 1 hour in the refrigerator. Longer is not better past that point; the color dulls and the leaves lose their clean edge.

  6. 6

    Plate with broth

    Lift the spinach out in neat bundles and set them slightly off-center in small bowls. Spoon over a little of the steeping dashi, just enough to pool lightly at the bottom. Finish with katsuobushi if using, and serve cool or at room temperature.

Chef Tips

  • Choose spinach with glossy leaves and firm stems, not limp bunches with yellow edges. Sourcing first, always. This dish has nothing hidden.
  • For a meatless table, use konbu and dried shiitake dashi and leave off the katsuobushi. That is honmono in the temple-kitchen line, not a compromise.
  • If using regular dark soy sauce instead of usukuchi shōyu, start with 2 teaspoons. It has a deeper color and can darken the broth faster than you expect.
  • Serve in small portions. Ohitashi is a quiet green note beside rice and soup, not a heap of spinach pretending to be lunch.

Advance Preparation

  • The seasoned dashi can be mixed a day ahead and kept refrigerated.
  • The spinach can steep up to 1 hour before serving. After that, drain it and store it separately from the broth to protect the color.
  • Leftovers keep one day refrigerated, though the green will dull. Serve them cool rather than reheating.
