How to Store Watercress at Home
Learn how to store watercress correctly so that you can keep it fresh as long as possible and avoid it turning into a pile of green slime overnight! Watercress is an expensive but highly tasty and nutritious addition to any salad or garnish. However, watercress is 93% water and so it spoils very quickly and needs treating rather differently from your other salads.
Watercress Facts and Nutrition:
Watercress is a semi aquatic plant that grows naturally in running water at the edges of streams and rivers. The scientific name is Nasturtium officinale which means it is related to mustard, cress and radish….and this gives us some clues as to why it is so tasty! Watercress is just jam packed with nutrients particularly Vitamins A and C as well as iron, calcium, iodine and folic acid. Basically it is just really good for you and acts a s a powerful stimulant to the digestive system, is a mild diuretic and is thought to have cancer suppressing properties.
Watercress was first commercially cultivated in 1808 in the UK by William Bradbery along the river Ebbsfleet in Kent. It rapidly became very popular and production quickly spread to other countries so that by the 1940’s Huntsville Alabama was regarded by many as the Watercress Capital of the World!
Traditionally watercress is sold as bunches of the freshly cut stems…usually tied together with string or an elastic band (These are good to keep for re-use!!). More recently supermarkets have started selling watercress in plumped up plastic bags in order to protect the delicate leaves from being crushed.
Being such a useful and nutritious plant it is important to learn how to store watercress at home.
How to Store Watercress for as Long as Possible:
Fresh watercress soon wilts if it is left out of water for any length of time. Equally, damp watercress can turn into a nasty slimy mess overnight if you try to store it like other salads…so what is the trick?
The first thing to do with watercress when you get it home is to untie the bunch or take it out of the bag and pick it over to remove any yellow, wilted or crushed leaves. Anything that looks even vaguely slimy needs to be picked off immediately other wise it will spread rapidly. Do not wash the leaves or let them get wet!
Method 1 – Store in a Plastic Box:
After picking over the leaves gently dab them dry with a clean cloth and put them in a plastic storage container, close the lid and and put the box in the salad compartment of the fridge. It is important to NOT ADD ANY WATER to the box! Like this the leaves should keep fresh for two or three days. Each time you use some just check that the remaining leaves are ok and remove any that have gone yellow.
Method 2 – Store in a Jug of Water & Cover with a Plastic Bag:
Since watercress grows in water it lasts well if the bunch is stored in a jug of water and covered with a plastic bag. With this method it is important to keep the leaves dry…do not mist them….and change the water in the jug every day. If possible store the covered jug in a cool but light place. Like this the watercress should last longer than if stored in the fridge….typically 3 or 4 days.
Checklist for How to Store Watercress:
- Deal with the watercress as soon as you get it home…any delay will reduce the time it stays fresh
- Remove all yellow leaves and slimy bits
- Keep the leaves dry….only wash them immediately before use
- Short term storage in a plastic box in the salad drawer of the refrigerator works well
- For maximum storage put the cress stems in a jug of water and cover with a plastic bag
Can I Grow Watercress?
If you look at the watercress stems carefully you will sometimes see tiny roots growing out from the node between the stem and a leaf. Both commercially and in the wild watercress needs flowing water to flourish. However, you can keep some of these stems with roots and put 4 or 5 into a six inch pot standing in a saucer of water. Every few days completely replace the water. Pinch the tops out of the cress and eat them….then after a few days you should start noticing that side-shoots appear. Eventually the leaves will get big enough to eat and will give you enough for a garnish!
