So, I've mentioned before, I love the Martha Stewart Living: Food magazines. They're filled with proven recipes that are easy and fast.
I have been living off the buttermilk ranch recipe from the June issue all month. The base is just 2 cups buttermilk, 1 cup sour cream, a half cup of mayo, salt and pepper to taste. But then you add fun stuff, like Parmesan cheese, or fresh herbs, or avocado, or bacon, or whatever, to it, to make it your own.
I have been using this on every shred of lettuce in the fridge, coating cooked and cooled green beans with it, even dipping pizza crusts into it. What can I say, it's tangy, salty goodness.
