Choi Sum is a green leafy vegetable and a member of the mustard and cabbage family. It is delicious cooked but whole leaves can also be used raw in salads. Common in Chinese cuisine, its bright green leaves ensure that any dish is more vibrant, tasty and enticing. The taste of choi sum is mild yet refreshing, with a flavour profile mid-way between cabbage and spinach. The leaves contain calcium, fibre and Vitamin A proteins, meaning it's a perfect addition to stir-fries and mixed vegetable dishes. The UK choi sum season runs during our summer and autumn, with Spanish crop available across the winter and spring months. Curious fruit and veg – delicious, fresh and picked by experts.
