Question: is arugula the same as watercress?
Answer: They're both peppery greens that are delicious in a salad, but arugula and watercress aren't quite interchangeable—arugula stands up to heat better (watercress can quickly turn to mush) and packs a spicier punch. Often used as a garnish, watercress is actually a nutrient-packed superfood that is cultivated in water.
