Herring-and-Potato Salad With Brown Butter

Preparation

1. Step 1

   Bring a large saucepan of salted water to boil. Drop in potatoes, turn down heat to medium and cook until tender, about 25 minutes. Drain, allow to cool and cut into 1-inch chunks. Place in a large bowl.

2. Step 2

   Melt butter in a small skillet over medium-low heat. Cook until butter turns golden brown, 2 to 3 minutes. Let cool.

3. Step 3

   Slice dark greens from onion and cut some into slivers for garnish. Trim roots and discard. Cut bulb in half lengthwise and slice into slivers (about ¼ cup).

4. Step 4

   In a bowl, whisk together crème fraîche, horseradish, lemon zest and juice, kosher salt and pepper.

5. Step 5

   Add the onion, herring and chives to the potatoes. Toss the crème fraîche dressing with the potato mixture and combine well. Pour the butter over the mixture and toss gently. Garnish with potato chips and onion greens.
