Tips & Variations

For a thinner dressing, add more buttermilk gradually until you reach your preferred consistency.

Try adding a teaspoon of grated Parmesan cheese for extra richness.
Fresh herbs like parsley or chives can brighten the flavor when stirred in just before serving.
If you prefer a spicier kick, add a pinch of red pepper flakes or a dash of hot sauce.

Storage

Store the dressing in an airtight container in the refrigerator for up to one week. Stir or shake well before each use, as separation may occur. This dressing is best served chilled but can be brought to room temperature for easier mixing.
