Watercress

Watercress grows in streams and ditches, however, recently it is now grown commercially.

What to look for

Choose fresh looking bunches with healthy stems. The leaves should be green, showing no signs of yellowing or wilting.

Availability

All year; best supplies, May - December.

Store

Refrigerate in plastic 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 and sandwiches, used as a garnish, added to soups and sauces, and used instead of spinach in omelettes, quiches and pancake fillings.

Suggested cooking methods

Boil, microwave, steam.
