Kohlrabi

The name translates as ‘turnip cabbage’ and the mild, sweet flavour is somewhere between a turnip and a waterchestnut, with a crisp, crunchy texture. It can be found in two colours, pale green and the less common purple. Larger bulbs can be tough, so select a medium-sized one that feels heavy for its dimensions. The leaves should be crisp-looking and intensely green. Avoid any bulbs that have soft spots or yellowing leaves.
