What Is Aburi Sushi and Why Searing Works

Aburi (炙り) means "flame-seared". The chef torches the surface of the fish, melting fat and caramelising the edges, while the inside stays raw. It is one of Hong Kong's favourite sushi styles.

At a glance. What: torched surface, raw centre. Why it works: heat melts fat and adds smoky, caramelised flavour. Best fish: fatty — salmon, salmon belly, toro, scallop, engawa, mackerel. Not for: anyone avoiding raw fish — it's still raw inside.

Why searing works

A blowtorch or charcoal heats only the surface. Fat just under the skin melts and turns aromatic, and sugars and proteins brown, adding roasted flavour. The centre stays cool and raw, so you get contrast — warm and crisp outside, soft inside.

Best fish for aburi

Salmon and salmon belly — the classic. Toro — melts beautifully. Scallop — turns sweet and nutty. Engawa — the fatty fin muscle. Mackerel — smoky skin. Wagyu — often seared at chains. See salmon vs salmon belly and scallop sushi.

Aburi in Hong Kong

Aburi is everywhere. sen-ryo's grilled sushi lunch set includes four aburi pieces — salmon belly, red shrimp, scallop and eel. Sushiro's premium sets list broiled fatty salmon, and its Opanchu Usagi campaign added an Aburi Basil Duo of salmon and shrimp at HKD 17 from 6 October 2026. See sen-ryo menu.

Toppings: aburi salmon loves Japanese mayo, lemon or a pinch of salt. Soy is often unnecessary.

At home: a kitchen blowtorch works. Keep the flame moving, and sear for just a few seconds.

Seared is not cooked. Aburi sushi is still raw in the centre. Pregnant women and young children should choose fully cooked sushi.
