1 pkg Hidden Valley Ranch dry mix (buttermilk recipe)
2 c mayonnaise
1 c buttermilk (*or sour milk)
1/2 t fresh cracked pepper
1/4 t cayenne pepper
1/4 t garlic powder
Combine all ingredients in a small bowl, mix well. refrigerate for at least an hour before serving - it needs time for all the flavors to marry.
*Sour milk. If you don't have buttermilk on hand (for any recipe) you can substitute the same measurement of buttermilk called for (in this recipe 1 c) regular milk and add 1T lemon or lime juice to it. In some recipes, using this substitute can make it a little tart - just balance that with a bit of sugar.
