RECIPE TIPS
Ingredient Notes
Mayonnaise. Use Hellman's or Best Food mayo.
Sour cream. Daisy sour cream is my favorite. It has the freshest sour cream flavor.
Buttermilk. I like full-fat Bulgarian-style buttermilk. If you don't have buttermilk you can use whole will and 2 teaspoons of lemon juice.
Recipe Variations
Ranch Dip: To make ranch dip, simply leave out the buttermilk. You will end up with a thicker ranch that is perfect for dipping crudites (sliced veggies.)
Buffalo Ranch Dressing: Add 1/2 teaspoon of paprika and 1/8-1/4 teaspoon of cayenne pepper.
Chipotle Ranch Dressing: Add 2 teaspoons of dried chipotle pepper, 2 teaspoons of taco seasoning mix, and 2 tablespoons of hot sauce like Chipotle Cholula.
