Potato Salad with Radishes, Lemon & Dill

2 pounds unpeeled smallish red potatoes, scrubbed
Kosher salt
2 inner ribs celery and their tender leaves, finely chopped (about 1/2 cup)
3/4 cup thinly sliced radishes (about 6 small radishes)
3 scallions (white and tender green parts), chopped
2 tablespoons chopped fresh dill
1/4 cup heavy cream, well chilled
1/2 cup mayonnaise
1-1/2 teaspoons Dijon mustard
1-1/2 tablespoons fresh lemon juice
2 teaspoons grated lemon zest
Freshly ground pepper (black or white)

Put the potatoes in a medium saucepan, cover with water by an inch or two, add a large pinch of salt, and bring to a boil. Reduce the heat to medium, partially cover, and cook until the potatoes are tender, about 20 minutes (test for doneness as described at right). Drain the potatoes and let them cool. You can drain them on a cooling rack set over or in your sink, which will avoid squashing the tender potatoes (as often happens with a colander) and also lets the potatoes cool quickly.

When the potatoes are at room temperature, cut them into 3/4-inch chunks and put them in a mixing bowl. Add the celery, radishes, scallions, and dill and fold gently to distribute; set aside.

In a small bowl, whisk the cream until frothy but not at all stiffened. Whisk in the mayonnaise and mustard. Add the lemon juice, zest, 1/2 teaspoon salt, and pepper to taste. Pour the dressing over the salad and fold it in with a rubber spatula. Taste for seasoning. Serve, or cover and chill for up to a day.

Serves six; yields about 6 cups.
