Sushi, piece by piece

HOW TO READ THIS DISH

Four things to know first

Place

Edomae techniques grew around Tokyo; seafood associations vary widely by coast and season.

Compared with food abroad

Unlike sashimi, sushi includes seasoned rice. Many rolls found abroad are modern local styles; neither is a test of authenticity.

Ordering

For a first meal, mix cooked, mild and richer pieces. At conveyor-belt shops, check the touch screen and plate price before ordering.

Allergy cue

Fish, shellfish, egg, soy, wheat and sesame may appear; shared knives, boards, fryers and sauces can create cross-contact.
