How it is used
Food
Rating: 4
Leaves - raw. Used in salads, they are very strongly flavoured of cress. The leaves have a hot flavour, very similar to rocket (Eruca vesicaria sativa) but more strongly flavoured - they make an excellent addition to a mixed salad but are too strong to be used in quantity on their own. The plant is very productive, producing leaves from early spring until the autumn.
