In a medium mixing bowl, add ½ cup of crumbled blue cheese, ½ cup of mayonnaise, and ¼ cup of sour cream. Squeeze in the juice of half a fresh lemon, and grate 1 clove of garlic directly into the bowl. Sprinkle ¼ teaspoon of salt and ¼ teaspoon of black pepper for flavor. Using a fork, gently mix all ingredients until well combined.

As you stir, observe the dressing's texture; it should be creamy yet still have visible bits of blue cheese for character. If you prefer a thinner consistency, gradually add 1 to 2 tablespoons of milk, stirring continuously until it reaches your desired thickness.

Carefully transfer the finished dressing into an airtight container, scraping down the sides of the bowl to ensure no delicious bits are left behind. Seal the container tightly to maintain the freshness and flavor.

When you’re ready to enjoy your homemade Blue Cheese Dressing, give it a good stir to re-mix any settled ingredients. Drizzle it liberally over a fresh garden salad, or use it as a zesty dip for vegetables and wings.
