FAQ
Q. Please do you have to fry it with the skin of the soya beans?
A. Yes because it's easier to break the seeds so that the skin is easily blown out with a tray when roasted until dry, than manually, as it is believed that the skin is harmful to health. Roasted soybeans are very beneficial to health.
