Instructions

• In a medium bowl, place 1 cup mayonnaise and 3/4 cup vegetable oil. Whisk them together until smooth and well blended; to help the dressing emulsify, slowly pour the oil into the mayonnaise while whisking.
• Add 3/4 cup buttermilk, 2 tablespoons grated Romano cheese, 2 tablespoons crushed dried basil, 1 teaspoon minced garlic, and 1/2 teaspoon salt to the bowl.
• Stir the mixture until all ingredients are evenly combined and the dressing is smooth.
• Add hot pepper sauce to taste, starting with a small amount and increasing until you reach your preferred level of heat. Stir to incorporate.
• Transfer the dressing to a covered container or jar and refrigerate overnight (or at least 8 hours) to allow flavors to blend.
• Before serving, stir or shake the dressing well and taste; if needed, adjust by adding more hot pepper sauce or a pinch more salt.
