Grilled Scallop Skewers (帆立串焼き, Hotate Kushiyaki)

Created by

Hotate kushiyaki asks for one good scallop, hot fire, and restraint. Brush the butter-shōyu glaze only at the end, then stop when the center turns milky white.

Good hotate don't need coaxing. They come to the grill already sweet, briny, and full of their own clear juice, especially when cold-water scallops are in shun, at their prime. Choose dry sea scallops that smell clean and faintly sweet, not like a chemical rinse. Sourcing first. With shellfish, the best technique is mostly the courtesy of not spoiling what you bought.

The fear here is overcooking, and it is a reasonable fear. A scallop moves from tender to rubber in the time it takes a serious person to adjust their glasses. So we give it hot direct heat, one turn, and a glaze only at the end. Brush butter and shōyu on too early and the soy catches, the milk solids darken, and the sweetness turns bitter. Brush it late and it lacquers the surface without hiding the scallop.

Kushiyaki means skewer-grilled, and it is the method, not the menu. Three scallops on a stick, a little salt, a little butter-shōyu, and the judgment to stop when the center changes from clear to milky white. Serve them as yakimono, the grilled note in a meal, or beside the first drink before rice. Leave them room on the plate. 本物 (honmono, the real thing) is often this plain.

Terajima Ryōan's 1712 encyclopedia Wakan Sansai Zue records the old explanation of hotate-gai as a shellfish that raises a sail, using one valve to move, a beautiful mistake that stayed in the name. Modern hotate cookery is closely tied to Hokkaido and Aomori's Mutsu Bay, where twentieth-century aquaculture made large, sweet scallops common on the Japanese table. Butter-shōyu is a modern northern pairing tied to Hokkaido's dairy industry, promoted by the Meiji government from the late nineteenth century, while kushiyaki simply names the skewer-grilled method.

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

Ingredients

large dry sea scallops

Quantity

12 (about 450g)

side muscles removed

fine sea salt

Quantity

1/4 teaspoon

neutral oil

Quantity

1 tablespoon, plus more for the grill

unsalted butter

Quantity

2 tablespoons

shōyu (Japanese soy sauce)

Quantity

1 tablespoon

sake

Quantity

1 tablespoon

mirin

Quantity

1 teaspoon

sudachi, yuzu, or lemon (optional)

Quantity

1 small

cut into wedges

Equipment Needed

  • Bamboo skewers (takegushi), soaked, or flat metal skewers
  • Shichirin or yakidai charcoal grill, or a very hot gas grill or cast-iron grill pan
  • Small brush for glaze
  • Instant-read thermometer, optional

Instructions

  1. 1

    Soak the skewers

    Soak 4 bamboo skewers in water for 30 minutes if you're cooking over charcoal, or use flat metal skewers and skip the soak. Bamboo chars quickly over direct heat, and soaking buys enough time for this short cook. Flat skewers are even better, because the scallops won't spin when you turn them.

  2. 2

    Dry the scallops

    Keep the scallops cold until you need them. Remove the small tough side muscle from each one, then pat the scallops dry. Salt both flat faces lightly and rest them on a rack for 10 minutes. Pat them dry again. Surface moisture is the enemy here: it keeps the scallop from browning and makes it boil in its own water instead of grilling cleanly.

    The side muscle is edible but chewy. Pulling it away leaves the scallop tender from edge to center.
  3. 3

    Make the glaze

    Melt the butter gently in a small pan. Stir in the shōyu, sake, and mirin, then let it bubble quietly for 30 seconds. This softens the raw edge of the sake and helps the glaze cling. Spoon 1 tablespoon into a clean small dish for finishing, then keep the rest for brushing at the grill.

  4. 4

    Thread the scallops

    Thread 3 scallops onto each skewer through their sides, leaving the broad flat faces open to the fire. Leave a little space between them. The flat face gives you browning, and the small gaps let heat move evenly instead of trapping juice between crowded scallops. Brush the scallops lightly with oil.

  5. 5

    Grill the first side

    Heat a charcoal grill, gas grill, or cast-iron grill pan until very hot, then oil the grate. Lay the skewers flat-side down and leave them alone for 90 seconds to 2 minutes, until the underside has clear grill marks and the edges begin turning opaque. Don't fuss with them. The surface needs quiet contact before the inside overcooks.

  6. 6

    Glaze and finish

    Turn the skewers once and grill the second side for 60 to 90 seconds. In the last 30 seconds, brush with the butter-shōyu glaze, turn briefly, and brush the other side. Pull the skewers off the moment the centers change from clear to milky white and the scallops still feel springy, not firm.

    The color change is the detail that decides the dish. Wait until the scallop feels hard and you've already passed tenderness.
  7. 7

    Rest and serve

    Rest the skewers for 1 minute, then brush with the clean reserved glaze. Add a few drops of sudachi or yuzu if you have it. Lemon is the sensible stand-in, not the same thing. Serve at once, with the scallops glossy but not drowned. The glaze is a shine, not a sauce.

Chef Tips

  • Ask for dry-packed sea scallops, large and even in size. If they're sitting in milky liquid, buy another day or change the dish. A wet-packed scallop gives water before it gives sweetness, and nothing good is hidden under butter.
  • Hotate shun shifts by coast. Hokkaido scallops are excellent through cold months, while Aomori's Mutsu Bay is famous for spring and early summer landings. Ask what came in bright, firm, and glistening fresh.
  • Binchōtan charcoal gives the cleanest heat if you have it. A very hot gas grill or cast-iron grill pan still works. The important thing is direct heat and a short cook.
  • For guests who need stricter seafood safety, cook scallops to 63°C/145°F. They will be firmer, but the meal will be more honest for saying so plainly.

Advance Preparation

  • The butter-shōyu glaze can be made up to 2 days ahead and refrigerated. Warm it gently until loose before grilling.
  • Bamboo skewers can soak earlier the same day. Keep them wrapped in a damp towel until you cook.
  • Scallops can be cleaned and set on a towel-lined tray up to 2 hours ahead. Keep them covered and cold, and salt only 10 minutes before grilling.
