About this class
This online Japanese cooking class is about raw fish, aged first. Gareth hangs Japanese hamachi and bluefin tuna in a fridge lined with Himalayan salt, where air circulation and low humidity dry the skin within 12 to 24 hours. The hamachi shown has aged for two weeks.
Each fish is broken down on camera, then served raw five ways: hamachi loin seared for under a minute with teriyaki, hamachi belly with a rice vinegar sauce, tuna akami folded around pickled nashi pear, chutoro on sushi rice, and tuna belly with olive and jalapeño.

““The most important part of aging fish and meat is air circulation, obviously, a dry, low-humid atmosphere.””
