Are Japan’s room-temperature curry packets the boxed lunch heroes we’ve been looking for? [Taste test]

Curry and rice are a classic combo, but packing a lunch with curry can be tricky due to the roux and aroma leaking from the container. Miyajima Shoyu Co., a Tokyo-based condiments maker, may have a solution with their Hitokuchi Series. This series includes ready-to-eat curry, stew, and hayashi rice sauce (similar to tomato sauce) packets that can be stored at room temperature and eaten without reheating. With a shelf life of over a year, these packets are perfect for taking with you on trips or for camping.

The Hitokuchi packets are easy to open and have a thick consistency that prevents them from dribbling out. The curry is mild, fitting Japanese curry flavors, and is enjoyable even at room temperature. The Hayashi has a surprising tomato tang but is well-balanced with sweetness. Lastly, the Stew is creamy and surprisingly enjoyable eaten at room temperature, though it's usually served hot in Japan.

While each packet only contains 30 grams of sauce, it's enough for a change of flavor if you have leftover rice. However, for a full meal, you'll likely need three packets. The packets are strictly roux/sauce, so any additional toppings need to be added separately. Despite this, the Hitokuchi Curry packets provide a tasty alternative to traditional curry meals, available for 1,340 yen for a 10-pack on Amazon Japan.
