Also known as the “phantom citrus fruit”, naoshichi are a rare sight even in Japan, with only 100 tonnes produced annually in the prefecture of Kochi. The flavour of naoshichi is most comparable to lime with its unique sour flavour, high acidity, mild bitterness and touch of sweetness. In Japan, naoshichi is typically used for its juice, which is mixed into rice in chirashi zushi and used in vinegared dishes.
Pastry maestro Janice Wong has been working with this rare Japanese citrus since 2013, infusing its bitter and sour notes in the desserts at the Janice Wong Dessert Bar in Shinjuku, Tokyo. It is one of her favourite citrus fruit to work with. “Every time I use it, I understand its versatility and flavours more. It is very sour and not as sweet as yuzu and has its own unique flavour compared to lemons,” she says.
In savoury dishes, the acidity of naoshichi cuts through fattiness and works well with fish dishes. Wong says: “Naoshichi adds a sharp brightness to the dish and allows a sweet or oily fish to achieve a good balance of flavour.”

Although naoshichi is currently not imported to Singapore, you can easily replicate Wong’s recipe for handmade naoshichi noodles with lime as a substitute. These bright and chewy handmade noodles work well in both hot and cold dishes, adding a citrusy zing to hot soups or cold noodle salads.
