- 1 ½ teaspoons Dijon mustard

- ⅓ cup scallion or spring onion, thinly sliced

Prepare the Potato Salad
Boil potatoes in thoroughly salted water until tender, about 15-20 minutes. Rinse and cool. Once cool, cut potatoes in half.
Toss potatoes with the additional tablespoon of chopped capers, sliced scallions, and about ½ the dressing (you’ll have extra for another use or more potato salad). Refrigerate for at least 2 hours before serving so salad is nice and chilled and absorbs the rich flavor of the dressing.
When ready to serve, heat about a ½ inch of neutral oil in a small shallow skillet or frying pan. Gently fry rosemary springs until vibrant green, about 30-40 seconds, over medium heat. If the heat is too high, sprigs will turn brown very quickly. Remove the sprigs from the oil with tongs and set them on a paper towel to absorb excess oil. Sprinkle lightly with kosher salt. Garnish salad with frizzled rosemary leaves that should fall right off the sprigs. Finish with flaky sea salt like Maldon.
Create the Zesty Dressing
To create the dressing, use an immersion hand blender or regular blender to combine buttermilk, lime zest and juice, Dijon mustard, honey, ⅓ cup scallion, garlic, and 1 teaspoon capers with juice. Slowly stream in grapeseed oil while blending. Season with salt and pepper.
More Tips from Chef Marissa Lippert
What was the inspiration behind this recipe?
I wanted a fun, vibrant side dish to complement any barbecue, picnic, or beach gathering. This twist on the traditional potato salad is light, flavor-packed, and aesthetically pleasing, so it can easily go from being a daytime dish to an evening offering.
What does frizzled mean?
Frizzled is simply a fancy way of saying fried. Herbs take on a unique texture when very lightly fried in oil. This method brings out their natural aromatics and offers a dynamic, crispy texture to dishes.
