Make Ahead Tip: To make ahead: Cover and refrigerate dressing for up to 1 week.
Tip: Buttermilk is a thick, tangy cow's-milk dairy product. Find both low-fat and nonfat versions in the dairy section of the supermarket. You can replace buttermilk in any recipe with an equal amount of “sour milk.” Mix 1 tablespoon lemon juice or vinegar to 1 cup low-fat or nonfat milk. Or use buttermilk powder (found in the baking section) prepared according to package directions.
