Special Equipment

Ingredients

  • ½ cup (114 grams) sour cream
  • ¼ cup (56 grams) mayonnaise
  • ¼ cup (56 grams) water
  • 2 teaspoons (15 grams) buttermilk powder, see Recipe Notes
  • 1 (1) garlic clove, pressed or finely minced
  • 2 tablespoons (30 grams) lemon juice
  • ½ teaspoon (½ teaspoon) garlic powder
  • ½ teaspoon (½ teaspoon) Worcestershire sauce, or soy sauce
  • ¼ teaspoon (¼ teaspoon) black pepper, freshly ground
  • 1 to 1¼ cup (114 to 140 grams) blue cheese, crumbled, see Recipe Notes

Instructions

  • In a large bowl, whisk together ½ cup sour cream, ¼ cup mayonnaise, ¼ cup water, and 2 teaspoons buttermilk powder until smooth.
  • Press 1 garlic clove using a garlic press or mince it finely. Add the garlic in with 2 tablespoons lemon juice, ½ teaspoon garlic powder, ½ teaspoon Worcestershire sauce or soy sauce, and ¼ teaspoon black pepper Whisk well.
  • Stir in 1 to 1¼ cup blue cheese (crumbled).
  • The dressing tastes best if you let it sit in the fridge for a few hours, and will thicken as it ages. If the dressing is too thick, just add a teaspoon or two of water.
  • Storage instructions: Blue cheese dressing will last in the fridge for about a week in a tightly sealed container. This dairy-based salad dressing doesn't freeze well, so it's best to use it up and make more!

Recipe Notes

Instead of water and buttermilk powder, you can substitute ¼ cup of fresh buttermilk if you have it on hand, or ¼ of milk with a dash of lemon juice added to “sour” it.
Use 4 to 6 ounces (114 to 140 grams) of fresh blue cheese depending on how thick you'd prefer the dressing to be - use more or less  to suit your taste. You can also use English Stilton, Italian Gorgonzola, or French Roquefort instead of the blue cheese.
