This is not a sauce but thats how we use it. It really goes with the pork tenderloin great. 16oz sour cream 1 pkg ranch dressing mix 1 cucumber peeled seeded and diced equal parts of onion and celery 1-2 tsp fresh dill salt and pepper to taste Mix the sour cream and dressing mix together and in the mean time diced everything else up mix up together. Chill at least an hour before you plan to use it. It makes a great dip for veggies too.
