Whisk the Greek yogurt in a medium bowl for about 20 seconds until completely smooth and creamy.
Drizzle in the honey and whisk until no streaks remain.
Stir in the vanilla extract, lemon zest, lemon juice, cinnamon if using, and the pinch of salt.
Taste with a piece of fruit and adjust: more honey for sweeter, more lemon juice for brighter.
Cover and refrigerate 15 to 30 minutes if you have time, or serve right away.
Spoon into a small serving bowl and serve in the center of a platter of fresh fruit.
