Peppery watercress takes on an exotic twist with the flavors of ginger and fresh cilantro leaves in this easy-to-prepare salad.
Make the dressing: Whisk vinegar, sugar, salt, and pepper in a small bowl until sugar and salt have dissolved. Add cilantro, jalapeno, and ginger. Add oil in a slow, steady stream, whisking until emulsified.
Assemble the salad: Toss watercress, carrots, jicama, and 2 tablespoons dressing in a large bowl. Divide among plates. Serve remaining dressing on the side.
