A precise, repeatable thawing method.
The tuna comes out of the freezer still frozen and is brought to serving temperature step by step. The same routine, every time.
Rinse
Cold running water, while still frozen.
Salted water
40 g of salt per litre: Saku about 50 minutes, Chunk about 2 hours 15 minutes.
Pat dry and rest
Kitchen paper, then rest before cutting.
Portioning
Cut only what you need for service.
Fridge at 2-4 °C
Covered, until service.
Why salted water.
The bath in salted water at 40 g per litre is the step in the Maguro San protocol. Follow the specified salt concentration, water temperature and immersion time.

The cut.
From Saku, an even slice for sashimi and nigiri. From Chunk, cubes for poke or knife-cut tartare. Every video shows the technique, not just the result.
