Moreover, the method to remove the bitterness from the stir-fried fern is so simple- just blanch it in water and then soak it in cold water. People didn't pay much attention to fern in the past because it wasn't popular. But if a skilled chef studied it for a few days, they'd definitely crack the technique. Next year, I surely won't be making any money off selling stir-fried fern. It will probably just sell for one or two cents per jin."
