Our Genmai Udon noodles are the thickest of Japanese noodles with a delightful smooth chewy texture. Our Genmai Udon Noodles are made of sifted whole wheat flour, brown rice flour, sea salt and water, then gently kneaded. After the dough has rested for 2-3 hours it is kneaded again then rolled and cut into strands 5-6mm in width. The addition of brown rice flour makes these noodles tastier and more nutritious.
