Method
Place whole potatoes in the large stockpot and cover with cold water by at least 2cm. Add the 30g of salt. Bring to a boil over high heat, then reduce to a simmer.
While potatoes cook, whisk together olive oil, lemon juice, Dijon mustard, grated garlic, minced rosemary, and black pepper in the large mixing bowl until emulsified. Do not add the crème fraîche yet.
Check potatoes for doneness. A paring knife should slide into the center with zero resistance. Drain thoroughly in a colander.
Return the drained potatoes to the hot empty pot for 1 minute to steam off excess moisture. This ensures the dressing absorbs properly rather than sliding off.
Transfer the hot potatoes directly into the bowl with the vinaigrette. Using a potato masher or fork, gently smash the potatoes. Aim for a mix of creamy mash and chunky bite-sized pieces. Do not overwork.
Fold in the scallions, parsley, and crème fraîche. Toss gently until just combined. Taste and adjust salt if necessary (potatoes soak up salt aggressively). Serve warm.
Chef's Notes
- Dressing the potatoes while they are steaming hot is non-negotiable; as the starch molecules cool, they close up and won't absorb the vinaigrette.
- Yukon Gold or similar yellow-fleshed potatoes are essential here because they have a natural creaminess that russets lack and a fluffiness that waxy red potatoes lack.
- If you want the rosemary flavor to be more subtle, infuse it into the olive oil by gently heating them together, then discarding the leaves before making the dressing.
Storage
Refrigerator: 3 days — Flavor improves overnight, but texture may become denser.
Reheating: Gently warm in a microwave at 50% power or fold in a warm pan with a splash of water.
Troubleshooting
Texture is gummy or gluey
Cause: Potatoes were overworked or beaten too vigorously
Fix: Cannot be fixed completely, but folding in chopped crunchy vegetables (like celery) can mask the texture
Prevention: Smash gently and stop while chunks remain; do not use a food processor or electric mixer
Cultural Context
This dish reflects the Modern American 'farm-to-table' philosophy, stripping away the heavy mayonnaise of traditional picnic salads in favor of bright acids and fresh herbs. It borrows the French technique of dressing warm vegetables to maximize flavor absorption.
