Ina Garten'S Old-Fashioned Salad - cooking recipe

Ingredients

3 lbs small red potatoes
salt, to taste (kosher)
pepper, to taste (freshly ground)
1 cup mayonnaise
1/4 cup buttermilk (or white wine)
2 tablespoons mustard, dijon
2 tablespoons mustard, whole grain
1/2 cup fresh dill, chopped
1/2 cup celery, medium- diced
1/2 cup red onion, small-diced

Preparation

Place potatoes in boiling water, then lower the heat and simmer water until potatoes are barely tender, about 15 minutes; drain potatoes and keep them warm.
In a small bowl, whisk together the mayonnaise, buttermilk, Dijon and whole grain mustards, 1 teaspoon salt and 1 teaspoon pepper, set aside.
When cool enough to handle, cut potatoes into salad-size pieces, into a bowl and pour enough dressing over them to moisten.
Add the celery, red onion, 2 teaspoons salt and one teaspoon pepper.
Toss well, cover and refrigerate for a few hours for the flavors to marry.
