How to Prepare Watercress:
Simply rinse it thoroughly in cold water and use a kitchen knife to cut off any over-sized stems. Blot the watercress dry using paper towels or use a standard salad spinner. Once you’ve finished rinsing, you can prepare the watercress by lightly steaming it or eat it raw. Perfect for a sandwich or salad.
How to Prepare Arugula:
Steaming it in a saucepan or sautéing it in a skillet, and drizzling it with olive oil as a flavorful side dish. Other methods include wilting the flavorful leaves in a pot of hot pasta to add texture and a tasty kick, substituting arugula for basil in pesto sauce, and adding it to sandwiches for an extra boost of flavor.
