Milk + yogurt = fake buttermilk for Ranch dressing?
I want to make ranch dressing and the recipe calls for buttermilk, but I don't have any on hand. Would it be best to create fake buttermilk by adding lemon juice/vinegar to some some milk, or would it be better to combine plain whole milk yogurt with regular milk? I need about 1 3/4 cups. Ideas, foodpicklers?
