In a medium saucepan, combine cranberries, dates, and water. Bring to a boil over medium-high heat, then reduce to low. Simmer, uncovered, for about 10 minutes, stirring occasionally, or until cranberries burst and dates soften.
Remove from heat and let cool slightly.
Transfer to a blender with Dijon, orange zest, thyme, and garlic. Blend until silky smooth.
Transfer the dressing to a jar and start whisking in the balsamic vinegar gradually until the flavor is balanced to your liking. Then add the orange juice to achieve the desired brightness. Season with salt and pepper.
Thin with water if needed for a pourable consistency.
