Product Description:
The roots are cylindrical, though have sometimes been flattened. They are roughly 1.5 cm thick and may be up to 30 cm long. The outer surface is an earth brown or dark brown and bears irregular deep furrows. The head of the root bears the dense scars left by the stalk and shoots, and close to the head are dense transverse creases that grow scarcer further down. The roots often have breaks in the skin. They are light and supple, and snap with difficulty to reveal a rough fracture that is whitish in color. They are cut into fine transverse or oblique slices, or into sections that are then sliced lengthwise. The skin accounts for the greater part of the cross section. Slices that are stir-fried in earth are golden brown.
Quality:
The best roots are clean, long, and of even thickness and are sweet to the taste. The heads should be small and the skin a light, fresh color.
