Hard-Seared Diver Scallops with Smoked Morita Dashi & Charred Scallion Oil

Instructions

1. 1

   Place 12 oz dry-packed diver scallops (U-10 or U-12 size) on a paper towel-lined plate. Season all over with 1 tsp Kosher salt. Let them sit uncovered in the fridge. This dry-brining step draws out surface moisture—the mortal enemy of a good crust.

   5 min

   Tip: Never skip drying your scallops. If they hit the pan wet, you get steamed rubber instead of a mahogany crust.

2. 2

   In a medium saucepan, combine 2.5 cups water, 1 piece kombu, and 2 whole Morita chiles. Place over medium-low heat. You want to slowly coax the flavors out, bringing it to a bare simmer.

   10 min

   Tip: Don't let the kombu boil furiously; it can become bitter and slimy. Slow heating extracts the best glutamates.

3. 3

   Heat a dry, heavy skillet (cast iron or carbon steel) over high heat. Add 1 bunch scallions (Spring onions) and dry-char them until deeply blackened in spots and softened. Remove from heat.

   7 min

   Tip: We want actual char here. It echoes the smokiness of the Morita chile and adds a yakitori-like depth to the oil.

4. 4

   Just before the dashi hits a rolling boil, remove and discard the kombu. Let the chiles simmer for 3 more minutes. Turn off the heat, stir in 1 cup Bonito flakes (Katsuobushi), and let steep untouched.

   5 min

   Tip: Morita chiles and bonito flakes share an incredible smoke-dried DNA. Steeping them together builds massive, layered umami.

5. 5

   Roughly chop the charred scallions and transfer them to a blender. Add 4 tbsp Grapeseed oil and 0.5 tsp Kosher salt. Blend on high until vivid green, then strain through a fine-mesh sieve or coffee filter. Set the vibrant green oil aside.

   5 min

   Tip: If the oil gets too hot in the blender, it will lose its bright green color. Pulse it if your blender is very powerful.

6. 6

   Strain the steeped dashi through a fine-mesh sieve lined with a paper towel into a clean saucepan. Discard the solids. Season the clear broth with 1 tbsp Light soy sauce (Usukuchi) and 1 tsp Yuzu juice. Keep warm on very low heat.

   2 min

   Tip: Taste the broth—it should taste like a smoky, bright wave of the ocean. Adjust salt if necessary.

7. 7

   Wipe out your heavy skillet and place it over medium-high heat until it's ripping hot. Add the remaining 2 tbsp Grapeseed oil and let it heat until just starting to shimmer and smoke.

   3 min

   Tip: A hard sear demands high thermal mass. Cast iron or heavy stainless steel is non-negotiable here.

8. 8

   Remove scallops from the fridge and pat them completely dry with fresh paper towels one last time. Place them into the hot oil, pressing down gently for 2 seconds to ensure full surface contact. Step back and do not touch them for 2 full minutes.

   2 min

   Tip: The scallops will stick initially. When the Maillard reaction completes and the crust forms, they will naturally release from the pan.

9. 9

   Once a deep golden-brown crust has formed, flip the scallops. Immediately drop in 2 tbsp Unsalted butter. Tilt the pan and use a spoon to baste the foaming butter over the scallops for 60 seconds. Remove from the pan immediately.

   2 min

   Tip: The butter will brown rapidly, nuttifying the flavor and finishing the quick, gentle cooking of the scallop's interior.

10. 10

    To serve, pour a shallow pool of the warm Morita Dashi into wide bowls. Arrange the seared scallops in the broth. Use a spoon to dot the surface of the broth with the vibrant Charred Scallion Oil.

    2 min

    Tip: Serve immediately. The contrast between the crunchy, buttery crust of the scallop and the clean, smoky broth is pure magic.
