At FOB Sushi Bar, our Seared Salmon is a fan favorite. It offers the best of both worlds: the rich, raw texture of sashimi-grade fish combined with the smoky, caramelized complexity of a cooked steak.

In Japanese, this technique is called Aburi (meaning “flamed” or “torched”). Searing the fish, even for just a few seconds, completely transforms the flavor profile. The heat melts the high fat content of the salmon, creating a buttery, smoky sensation that needs almost no seasoning.

If you are a culinary adventurer and want to try this advanced technique at home, here is a step-by-step guide to mastering the Aburi sear.

1. The Right Cut of Fish

You must use a fatty cut, like Salmon Belly (the richest part). A lean cut will just dry out and taste overcooked. A fatty cut has enough oil to effectively fry its own surface when the heat is applied. Cut the salmon into standard 1/2-inch thick sashimi slices.

2. The Tool: A Kitchen Torch

You cannot do this under the broiler or with a lighter. You need a dedicated Butane Kitchen Torch. A torch allows for precise, concentrated heat that sears the exterior without cooking the interior.

• Safety First: Always work on a flame-safe surface, like a metal tray or slate board. Keep a clear workspace and ensure good ventilation.

3. Adding the Seasoning (Optional)

Traditionally, a tiny amount of seasoning is applied before searing. Heat interacts with the topping, creating a complex glaze.

• Miso Paste: A thin layer creates a deeply savory, nutty flavor.
• Mayonnaise: A small dot creates a creamy, caramelized, and slightly sharp crust (like on our famous signature rolls).
• Sugar: A micro-sprinkle results in a sweet, glassy brûlée finish.

4. The Aburi Technique

The goal is to apply intense heat to only the top millimeter of the fish.

• Distance: Hold the torch tip about 3 to 4 inches away from the fish.
• Angle: Hold it at roughly a 45-degree angle.
• The Motion: Sweep the flame back and forth quickly and smoothly. Do not linger in one spot. You want a light golden-brown color, not charcoal.
• Timing: For sashimi slices, you only need 2 to 3 seconds per slice. For nigiri (fish on rice), you want to sear just until the fat begins to bubble and the very tips of the rice grains get a light color.

5. Serving

Aburi sushi is best served immediately, while the seared top is still warm and fragrant, contrasting with the chilled raw interior.
