what are soba noodles made of
Soba is a Japanese noodle traditionally made with 100% buckwheat flour â this kind of all-buckwheat soba is called juwari soba. However, since the buckwheat seed contains no gluten at all, this makes it very tricky to work with as a flour, especially when attempting soba at home.i-hachi soba is another style that is made with roughly 80% buckwheat flour and 20% wheat flour. This is the kind of soba that Sonoko teaches in her workshops and the kind that we're making here.
