Selection
and storage

through March. At maturity, they are usually two to three inches in
diameter and weigh between 60 to 250 g.
This root
vegetable usually sold bunched or topped. In the markets look for fresh
roots that are small, firm, round and impart delicate sweet flavor.
Avoid larger as well as over matured roots as they are woody in
textured and excess in fiber which makes dishes unappetizing.

home, remove the top greens as they rob nutrients of the
roots.
The roots can be stored for few weeks at low temperatures (32° to 35°
F) and high relative humidity (95 percent or above). Use top greens as
early as possible as they lose nutrients rather quickly.
