Watercress is now grown commercially and available all year round. It also grows in streams and ditches, however, it should only be taken from clean water.
What to look for
Choose fresh looking bunches with healthy stems. The leaves should be green, showing no signs of yellowing or wilting.
Availability
Available: all year
High season: May to December.
Store
Refrigerate in paper bags. Alternatively, if the roots are still attached, place in a jar of water and do not refrigerate. Use promptly.
How to prepare
Wash well. Remove woody stalks and discoloured leaves. Use the medium to thin stalks and the leaves. Discard only the very coarse stalks; add these to stocks and soups for extra flavour.
Ways to eat
The dark green leaves have a peppery flavour. It can be eaten raw in salads, sandwiches, wraps and rolls. It is often used as a garnish, or in smoothies or juices, added to boil ups, stews and braises, soups and sauces. Use in place of spinach in omelettes, quiches and pancake fillings.
