In a medium bowl or a mason jar, add the mayonnaise, sour cream, and crumbled blue cheese. Use a fork or whisk to mix these ingredients until they are well combined.

Pour in the whole milk and freshly squeezed lemon juice, then sprinkle in the garlic powder. Whisk these ingredients together until fully blended.

Stir in a dash of salt, black pepper, and Worcestershire sauce, then mix well.

For a chunkier texture, gently fold in additional crumbled blue cheese; for a smoother dressing, mash the blue cheese against the sides of the bowl.

Cover the bowl or jar and refrigerate the dressing for at least 20-30 minutes to allow the flavors to meld.

Before serving, give the dressing a good stir. Adjust the consistency with more milk if needed.
