Homemade Buttermilk Ranch Dressing

Waste not want not, right? I occasionally have leftover buttermilk and wanted to figure out how to use up some of the remainder before spoilage occurs. Not one to consume most baked goods, I discarded any notion of making buttermilk pancakes or the like. But salads we eat, so The Mr. immediately thought about concocting a buttermilk ranch dressing (which BTW is also great with crudités, chips or even wings!)

At first glance you may cringe at the lengthy list of ingredients—luckily most are staple pantry items. All of the herbs we had growing in our garden, but they are easy enough to obtain from a local farmer’s market or the grocery store (or your neighbor’s garden??).

This version was found on garlicandzest.com but actually hails from a Chicago restaurant, The Publican. It’s cool, creamy, tangy, garlicky and, honestly, good enough to eat straight from the jar—but please use a spoon. Once you’ve made ranch dressing from scratch, you may never go back.
