It’s used often in simmered dishes, in pan-fried dishes, fried in tempura, served as a small dish in Japanese izakayas, and more. Candied renkon is also a traditional gift during the Chinese New Year. Renkon tastes mildly sweet; it absorbs other flavors well, though, which makes it well-suited to stir-fries and braised dishes that have other sauces and ingredients that have a more assertive flavor.
Beyond the main root, renkon’s starch is also useful for gluten-free baking or other cooking techniques that could require wheat flour. Meanwhile, lotus flower leaves are sometimes used as food wrappers for steamed dishes like Chinese sticky rice.
