Sliced lotus roots, known as "renkon" in Japanese, are a popular ingredient in Japanese cuisine, valued for their unique appearance, with a pattern of holes, and their crunchy texture. These slices come from the root of the lotus plant and have a mild, slightly sweet flavor.
Chefs utilize sliced lotus roots in a variety of dishes, such as tempura, stir-fries, and simmered dishes (nimono), and they are also often pickled. Their crisp texture and aesthetic appeal make them a favored ingredient for adding visual interest and a refreshing bite to meals.
