Where to Find Watercress in the Grocery Store
Watercress is typically found in the refrigerated produce section, often near other leafy greens and herbs like arugula, spinach, and parsley. It is highly perishable due to its high water content and is therefore usually sold in one of two main formats to preserve freshness.
First, you'll see it sold in loose bunches. This presentation is similar to how fresh herbs are displayed. The bunches might have their root balls intact or have cut stems. For added longevity, some stores will display these bunches with their stems in a small amount of cold water, much like a bouquet of flowers. A second common format is a sealed plastic bag or container, often with a moisture-absorbing packet to keep the greens from getting slimy.
Visual Indicators of Fresh Watercress
To select the highest quality watercress, pay close attention to its appearance. The visual signs of freshness are clear and easy to identify once you know what to look for.
Inspecting the Leaves
Fresh watercress leaves should be small, round to oval, and a vibrant, dark green color. They will appear perky and firm, never wilted or droopy. Avoid any leaves that show signs of yellowing, browning, or bruising, as these indicate the watercress is past its prime.
Checking the Stems
The stems are another excellent indicator of freshness. They should be crisp, firm, and pale green, often with a hollow feel. The stems should not be brown or mushy. While you may trim the thicker stems before use, their overall condition is a reliable metric for the bunch's health.
What to Avoid When Buying Watercress
Knowing what to avoid is just as important as knowing what to seek out. Here is a list of red flags to watch for when you are selecting your watercress:
- Slimy Texture: A slimy or slick feeling on the leaves and stems is a surefire sign of decay.
- Off-Putting Odor: Fresh watercress has a mild, peppery, and fresh scent. A strong, decaying, or sour smell indicates it is no longer good to eat.
- Yellow or Brown Discoloration: Any significant amount of yellowing or browning on the leaves signals that the watercress is old or has been improperly stored.
- Drooping or Wilting: A limp bunch of watercress, whether in a bag or a bunch, has lost its crispness and is losing its nutritional value.
- Dry or Brittle Stems: While stems should be dry to the touch, they should not be brittle or shriveled, which is a sign of dehydration.
Comparing Watercress to Other Greens
Watercress is often displayed near other leafy greens that can be confused with it. While it shares some characteristics with its cruciferous family members, a few key distinctions set it apart.
| Feature | Watercress | Arugula | Land Cress (Upland Cress) |
|---|---|---|---|
| Leaf Shape | Small, rounded, and compound leaves with a larger terminal leaflet. | Smooth-sided leaves with a rounded top, less lobed than watercress. | Can have more pointed, sometimes deeply lobed leaves compared to watercress. |
| Flavor Profile | Bright, peppery, and slightly bitter; mellows when cooked. | Often has a more pungent, stronger peppery and tart taste than watercress. | Typically much more peppery than the cultivated watercress found in stores. |
| Stem | Crisp, pale green, and hollow, allowing it to float. | Smaller, non-hollow stems that are not designed for aquatic life. | Stems are thicker and tougher than watercress, and not hollow. |
| Origin | Aquatic or semi-aquatic plant, growing in cool, shallow water. | Terrestrial plant, grown on land, though also part of the mustard family. | Terrestrial plant, often with a tougher texture and stronger flavor than its water-loving relative. |
Conclusion: The Freshest Watercress for Your Recipe
Choosing the best watercress is a straightforward process once you know the signs of freshness. Focus on vibrant, dark green leaves and crisp, firm stems while steering clear of any wilting, sliminess, or discoloration. Remember that its common packaging—loose bunches with roots in water or sealed bags—is designed to keep this highly perishable green at its peak. By following these simple tips, you can confidently select the freshest watercress for your next salad or soup, ensuring the best possible peppery flavor and nutritional punch for your meal. A great resource for further nutritional information is the Centers for Disease Control and Prevention's Powerhouse Fruits and Vegetables list, which highlighted watercress as the top-ranking green.
