Kohl Rabi
This knobbly bulbous brassica has a peculiar, alien-like look with its pale green colour and strange protruding stems. The name literally translates as 'cabbage turnip', but this belies its excellent juicy crispness and light flavour, which is slightly sweet and milder than both a cabbage and a turnip. This is a two-in-one vegetable - the leaves taste almost as good as the kohlrabi itself, and are very similar to Chard.
