1. Peel and finely grate the fresh ginger on a microplane. Mince the garlic the same way.
2. Add yogurt, mayo, ginger, garlic, lemon juice, lemon zest, rice vinegar, Dijon mustard, agave, white pepper, and salt to the blender.
3. Blend on high for 60–90 seconds until completely smooth.
4. Add water 1 tbsp at a time to reach your preferred consistency — thicker for dipping, thinner for dressing.
5. Taste and adjust — more lemon for brightness, more ginger for heat, more agave for sweetness.
6. Serve immediately or chill in a glass jar for 30 minutes for the best flavor.
