Unajū (鰻重, grilled eel in a lacquered box)

Unajū can look like ceremony trapped in lacquer: the red-black box, the shine of the eel, the price that makes people lower their voices. Don't let the box bully you. The cooking asks for only three honest things: eel worth grilling, hot rice, and tare reduced until it coats without smothering.

The one detail that decides the dish is the glaze. Brush the tare on in thin layers, then let the grill tighten each layer before the next one goes on. Too little and the eel tastes plain. Too much and the sugar scorches, the sauce turns sticky, and you've buried the fish under sweetness. We want lacquer, not syrup. There is a difference, and your nose will tell you before your pride does.

Sourcing comes first here. Buy freshwater eel, unagi, already cleaned and butterflied by someone who knows the work; raw eel blood is harmful, so this is not the fish for heroic home butchery. If fresh eel is out of reach, a good frozen kabayaki from a Japanese market is a sensible stand-in. Warm it carefully and refresh it with your own tare. That is still the dish's spirit. Another fish under eel sauce is not.

Eel has a funny season story. Wild eel grows rich toward the cold months, yet unajū belongs to high summer by custom, especially Doyō-no-Ushi no Hi, when people eat eel for strength against the heat. Both truths can sit in the same box. Rice below, eel in the middle, rice again, eel shining on top. Leave it room, close the lid for a minute, and let the fragrance gather.
