With aromatic fresh lemon syrup and tangy buttermilk as its foundation, this sweet 'n sour dressing comes together with less oil than a traditional vinaigrette. It's a great way to lighten up summer salads, whether served on their own or alongside heavier fare. I love it tossed with baby greens, diced mango, and crispy lemon candied pistachios, but it works well with salad fixin's of any kind.
