Selection and storage

Fresh turnips can be available year-round. However, fresher, and sweeter roots flood the stores in abundance from October through March. Completely grown tubers measure about two to three inches in diameter and weigh between 60 to 250 g.

Fresh tubers usually sold either in the bunch with top greens or topped. In the markets look for fresh roots that are small to medium in size, firm, round and impart delicate sweet flavor. Avoid larger as well as overmatured roots as they are woody in texture due to excess fiber content and, therefore, unappetizing.

Once at home, separate the top greens from the root as the greens rob nutrients off the roots. The roots can be stored for a few weeks at low temperatures (32°-35° F) and high relative humidity (95 percent or above). Use top greens as early as possible since they lose nutrients rather quickly.
