Ingredients
Method
- Cook the potatoes. Put the potatoes in a large pot and cover them with cold water by 1 inch, then stir 2 tablespoons salt into the cooking water. Bring it to a boil over high heat, then reduce the heat and simmer for 5 to 10 minutes, until the chunks are fork-tender with just a little resistance at the center. Drain and let them cool slightly.
- Whisk the dressing. In a medium bowl, whisk together the olive oil, mustard, lemon juice, mayo, vinegar, garlic, salt, and several grinds of pepper. Keep whisking until the mixture looks uniformly cloudy rather than separated.
- Dress and chill. Transfer the potatoes to a large bowl and pour in the dressing, stirring to coat. Add the celery, scallions, chives, and dill and stir to combine. Cover and refrigerate for at least 1 hour so the flavors can meld.
- Season and serve. When you’re ready to serve, season the salad to taste, adding more lemon juice if you’d like. Garnish with more chives and serve.
Notes
Cut the potato chunks as evenly as you can at 1½ inches. Within a 5 to 10 minute cooking window, small variations in size make a real difference between pieces that are still firm and pieces that have gone soft.
Chop the celery finely enough that it distributes through the bowl. Large chunks give you an occasional loud celery bite rather than consistent crunch throughout.
Reserve some chives when you chop, since the recipe calls for extra as a garnish at the end. Fresh, uncooked herbs scattered on top after chilling taste noticeably brighter than the ones that have been sitting in dressing for an hour.
This is designed to sit for at least an hour, which makes it a reasonable make-ahead dish, though the final seasoning step should always happen right before serving.
