In a medium bowl, whisk together the pomegranate juice, Dijon mustard, red wine vinegar, maple syrup, and kosher salt.
Slowly whisk in the olive oil 1 tablespoon at a time until fully combined and an emulsion forms. The dressing can be stored in the refrigerator for up to 2 weeks. Before serving, let it stand on the counter for a few minutes until it comes to room temperature and shake well before serving.
