Hakodate opened to foreign trade in 1859, but its real fortune swims past the city every summer: surume-ika, the Japanese flying squid, in shoals that made the port Japan's squid capital. The fleet fishes at night under banks of lights you can see from the mountaintop, and the morning market sells squid so fresh they're still changing color. Ika sōmen as a named dish — squid cut into strands and slurped like the wheat noodles it puns on — spread from Hakodate's market stalls and restaurants in the Shōwa years, and eating it over ice remains the city's standard summer breakfast.

This is the rare recipe where nothing is cooked and everything is technique. The strands must be cut along the body's length in single pulling strokes, cold and dry, on a board you've wiped twice. Done right, the squid turns from opaque to glass, sweet and faintly crisp, needing only ginger soy and maybe an egg yolk. It's knife practice disguised as breakfast, and Hakodate has been doing its morning drills for a century.

A long, sharp blade and one pulling stroke per cut — never a saw. Squid cut in a single motion stays glassy and snaps pleasantly; squid sawed through goes ragged and dull before it reaches the plate.

板前の一言 · A word from the kitchen

Ingredients材料

Serves 2

  • 2very fresh squid, sashimi grade — surume-ika is the Hakodate species; ask your fishmonger for sashimi-grade, or buy cleaned sashimi squid and skip the butchery
  • 4 tbspsoy sauce
  • 1 tbspgrated ginger
  • 1egg yolk or quail egg — optional, for the dipping sauce, Hakodate-style
  • finely sliced negi
  • shiso leaves — to line the plate
  • crushed ice — to serve over, in summer

Method作り方

  1. Step 1: Clean the squid

    Pull the head and innards from the body in one slow motion, remove the quill, and slip your fingers under the skin to peel it away. Rinse the tube quickly in cold water and dry it completely — water is the enemy of clean cuts.

  2. Step 2: Open the tube

    Slit the tube along one side and open it flat, inner side up. Trim the edges square. Chill it in the fridge for 15 minutes; cold, firm squid cuts far more precisely than room-temperature squid.

  3. Step 3: Cut the noodles

    With your longest, sharpest knife, slice the squid lengthwise — along the fibers, the length of the body — into strands 2 to 3 mm wide, each in a single pulling stroke. Take your time; this is the entire dish.

  4. Step 4: Plate cold

    Pile the strands loosely on shiso over crushed ice, like a nest of glass noodles. Height and looseness matter — a flattened pile eats like sashimi, not sōmen.

  5. Step 5: Mix the sauce and eat

    Stir the ginger into the soy, add the egg yolk if using, and scatter the negi. Lift the strands with chopsticks, dip like noodles, and eat immediately — the texture is at its best for about twenty minutes.

Questions from the kitchen

Why cut squid like noodles at all?

Texture, mostly. Thin strands turn squid's density into something slippery and cool that you slurp rather than chew, and every strand carries more sauce than a thick sashimi slice ever could. It also makes half a squid look like a feast, which no fishing port ever objected to.

Is it safe to eat raw squid at home?

Only with sashimi-grade squid from a fishmonger you trust. Anisakis is a real concern in raw squid; commercial freezing kills it, which is why previously frozen sashimi-grade squid is the sensible home choice — the texture loss is smaller than the peace of mind gained.

What if my knife skills aren't there yet?

Cut wider strands — 5 mm ribbons still eat beautifully — and don't apologize. The single-stroke pull matters more than the width; practice the motion slowly and the thinness arrives on its own.
