Instructions

1. 1

   Select and prepare potatoes

   Choose waxy potatoes: Yukon Gold, fingerlings, or red-skinned varieties. These hold their shape when sliced. Starchy russets will crumble into the dressing and create an unpleasant paste. Scrub the potatoes well but leave the skins on. They add color, texture, and nutrients. Cut any larger potatoes in half so all pieces cook at the same rate.

   Size matters here. Aim for pieces roughly the size of a golf ball. Uniformity ensures even cooking.

   Cook potatoes properly

   Place potatoes in a large pot and cover with cold water by two inches. Add two tablespoons of kosher salt. Starting in cold water allows the potatoes to cook evenly from edge to center. Bring to a boil over high heat, then reduce to a gentle simmer. Cook until a paring knife slides through the center with no resistance, 18 to 25 minutes depending on size. The potato should not break apart when pierced.

   Never start potatoes in boiling water. The exterior will turn to mush before the center cooks through.

   Build the vinaigrette

   While potatoes simmer, make your vinaigrette. In a large serving bowl, combine the vinegar, Dijon mustard, whole grain mustard, minced shallot, salt, and pepper. Let this sit for five minutes. The acid will soften the shallot's bite. Now whisk in the olive oil in a slow steady stream, beating constantly until the mixture emulsifies into a creamy, unified dressing. It should coat a spoon and hold together, not separate into oil and vinegar.

   The mustard is your emulsifier. It contains compounds that bind oil and vinegar together. Without mustard, your dressing would break.

   Drain and slice while hot

   The moment your potatoes are tender, drain them well and let them steam dry in the colander for two minutes. This removes excess moisture that would dilute your dressing. Working quickly while they're still hot, slice the potatoes into rounds about a quarter-inch thick. Use a sharp knife and confident strokes. Speed matters more than perfection here.

5. 5

   Dress the warm potatoes

   Add the hot potato slices directly to the bowl with the vinaigrette. Drizzle the white wine or stock over the potatoes. This additional liquid helps the seasoning penetrate. Toss very gently using a rubber spatula, turning from the bottom to coat every slice without breaking them apart. The potatoes will drink in the dressing visibly. You can watch them transform from dry and starchy to glistening and seasoned.

   Handle warm potatoes like you're folding egg whites. Gentle, deliberate movements. Aggressive stirring creates potato mash.
6. 6

   Rest and absorb

   Let the dressed potatoes rest at room temperature for at least 20 minutes, or up to one hour. During this time, the vinaigrette continues to absorb and the flavors marry. Gently fold the salad once or twice during resting. Taste and adjust seasoning. Potatoes absorb salt as they cool, so you'll likely need more than you think.

7. 7

   Finish with fresh herbs

   Just before serving, add the tarragon, chives, and parsley. Fold gently to distribute. The herbs should be added at the last moment to preserve their color and fresh flavor. Taste once more for salt and acid. The salad should be bright and assertive, not bland. A final drizzle of your best olive oil over the top adds sheen and richness.

   Tarragon is traditional and essential. Its anise notes define French potato salad. Don't substitute dried herbs here.

   Serve at proper temperature

   Serve the salad at room temperature, never cold. Refrigeration dulls the flavors and firms the potatoes unpleasantly. If you must make it ahead and refrigerate, pull it out one hour before serving and let it return to room temperature. The salad is beautiful mounded on a platter, or served family-style from the bowl you dressed it in.

Chef Tips

• •The quality of your olive oil matters tremendously here. This is not the place for a bland supermarket blend. Use something fruity and peppery that you'd happily dip bread into.
• •If your vinaigrette breaks, add another teaspoon of Dijon to a clean bowl and slowly whisk in the broken dressing. The mustard will re-emulsify everything.
• •This salad pairs beautifully with grilled fish, roasted chicken, or a simple steak. It also loves a glass of crisp Sancerre or dry rosé.
• •For a composed dinner party presentation, arrange the potato slices in overlapping rows on a platter rather than mounding them. Scatter herbs artfully over the top.
• •Leftover salad keeps refrigerated for two days, though you'll need to bring it to room temperature and refresh with a splash of vinegar and pinch of salt before serving.

Advance Preparation

• •The vinaigrette can be made up to three days ahead and refrigerated. Bring to room temperature and re-whisk before using.
• •The complete salad can be made four hours ahead and held at room temperature. Add fresh herbs just before serving.
• •If making a day ahead, refrigerate without the herbs. Bring to room temperature one hour before serving, taste for seasoning, and add fresh herbs at the last moment.
