Can I make this dressing ahead of time?
Yes, prepare it up to 3 days in advance and store in an airtight container in the refrigerator. The flavors deepen as it sits.
What can I substitute for blue cheese?
Gorgonzola, Danish blue, or Roquefort work well for a similar pungent flavor. Feta provides tanginess but less creaminess.
How do I adjust the thickness?
Add more buttermilk to thin it out for pouring, or use less buttermilk to thicken it for dipping.
Is this dressing dairy-free?
No, it contains mayo, sour cream, buttermilk, and blue cheese. Dairy-free versions would require plant-based substitutes for all three.
Can I use dried dill instead of fresh?
Yes, use 1 teaspoon dried dill instead of 1 tablespoon fresh. Dried herbs are more concentrated in flavor.
