What distinct seasoning is used in the vinegared rice for *Tosa Inakazushi*?
Answer
Yuzu vinegar
*Tosa Inakazushi*, or country sushi, showcases the culinary resourcefulness of mountainous Tosa where seafood was historically scarce. The key to its signature refreshing and simple taste lies in how the vinegared rice is seasoned, specifically utilizing *yuzu vinegar*. This bright, acidic component differentiates it significantly from many other sushi preparations. The toppings themselves, which include items like *Ryukyu* (pickled Indian taro stems) and Japanese knotweed, complement this citrusy base, highlighting earthy textures over seafood components.
