Masu zushiPressed trout sushi
Masu zushi is Toyama's famous ekiben, the boxed lunch sold at the station for the train ride: a round, flat cake of vinegared rice pressed under a layer of salted, vinegar-cured trout and wrapped in bright green bamboo leaves, cut into wedges like a pie. The fish is cured but raw, so use only fish sold as safe to eat raw and previously frozen, and keep everything cold; this version is not for pregnant women, young children or anyone with a weakened immune system. For a safer version, use hot-smoked trout fillet instead, which is fully cooked. The usual mistake is pressing the rice while it is still warm, which turns it mushy; cool it to body temperature first. Chef's tip: press the cake for a full hour under a heavy weight so it slices cleanly, then cut it with a wet knife.
