How to make Fried Fingerling Potatoes with Tarragon Sauce
Back to contentsBring potatoes, 60ml kosher salt, and 1925ml water to a boil in a large saucepan and cook until potatoes are tender, about 12 minutes. Drain; let cool completely. Halve potatoes lengthwise. DO AHEAD: Can be made 1 day ahead. Cover and chill.
