Broiled black cod collars over white rice, watermelon radish marinated in shiso vinegar, steamed broccoli, pickled ginger and a soy/citrus dipping sauce, which turned out to be entirely unnecessary.
The black cod collars, which look like a pile of charred birds in my photo, were an add-on item in my fish share. They were very good, if messy, to eat.
Pre-broil, two of them just got sprinkled with salt, the others got a 30-min miso/mirin/sake marinade. I have more in the marinade to cook tomorrow and see if that makes a difference.
