Creamy Blue Cheese-Tarragon Dressing
Make Ahead Tip: Cover and refrigerate for up to 1 week.
Shopping tip: Thick and creamy Greek-style yogurt is made by removing the whey from cultured milk. Because the whey has been removed, you can cook with Greek-style yogurt without the normal separation that occurs when cooking with regular yogurt. Both can be used in this recipe, but we recommend using Greek yogurt if it's available at your supermarket.
