Gari (ガリ, sushi ginger)

Gari begins with the ginger, not the vinegar. Use young ginger, shin-shōga, while it is at its prime: pale-skinned, tender, and tipped with a blush of pink. That color matters. In the real thing, the pickle's faint pink comes from the ginger itself meeting vinegar, not from a bottle of dye pretending to be helpful.

The dish looks like a small extra beside sushi, so people treat it casually. We shouldn't. Gari clears the mouth between pieces, especially when moving from lean fish to richer fish, or from one seasoning to another. It isn't there to cover bad fish. Nothing hidden. It is a clean pause, sharp and sweet enough to reset the tongue.

The one detail that decides it is thin slicing. Cut the ginger so thin it bends without breaking, and the vinegar reaches it quickly while the bite stays crisp. A brief blanch tames the raw fire without cooking away its snap. Then the amazu, sweet rice vinegar, does the quiet work while you leave it alone. Difficult? No. Only unfamiliar, and the jar will teach you by morning.
