Homemade Blue Cheese Dressing (with optional Mayonnaise)

First, make your mayonnaise (optional). Combine the egg yolks, 1 tablespoon white vinegar, a pinch of salt, a tiny lemon squeeze, 0.5 tablespoon of Dijon mustard, and 1.25 cups of a neutral oil. Use an immersion blender in a cup or jar and blend until you achieve a mayonnaise consistency. If you're skipping homemade mayo, use 1 cup of store-bought mayonnaise. 

In a separate bowl, whisk together the blue cheese dressing ingredients: 6-8 oz blue cheese, 1 cup buttermilk, 1 cup sour cream, 1 cup mayonnaise (either homemade or store-bought), 1/3 cup white wine vinegar, 0.5 tablespoon Bleu Cheese Wing Salt, 0.5 teaspoon garlic powder, 0.5 teaspoon onion powder, 1 teaspoon sugar, and salt and pepper to taste. 

If possible, let the dressing sit overnight in the fridge. This allows the flavors to fully develop and meld together, resulting in a richer and more delicious dressing.
