Tempura Sushi is a sushi shop at 20 Parumoana St in central Porirua, holding a 4.3 Google rating. At any good sushi counter the rice matters as much as the fish: it should be lightly seasoned with vinegar and kept at room temperature, as chilled rice turns firm and chalky and mutes the flavour. Shops that roll in small batches through the day are worth seeking out over cabinets of pre-packs that have sat for hours. Tempura rolls are best eaten soon after they are made, while the crumb is still crisp — a shattering batter is the mark of a fresh fry. Regulars learn to time their visit to the lunch rush, when turnover keeps everything at its best. On Parumoana Street in the middle of Porirua, this is a handy stop for a quick Japanese lunch or a box to take home.
