Grilled Fingerling Potatoes With Creamy Tarragon Vinaigrette Recipes

Steps:

• Put the potatoes in a large pot and cover with 2 inches of water and a tablespoon of salt, then set over high heat until it comes to a boil. Cook about 5 to 7 minutes. Drain potatoes, place on a baking sheet and allow to cool slightly, then halve the potatoes lengthwise. (You can do this the day before.)
• Meanwhile, cook the bacon in a sauté pan until crisp. Reserve bacon and, in a small bowl, 1 tablespoon of the rendered fat.
• Light a fire in a fire pit with a grill, or in a charcoal grill, or set a gas grill to high. If you have a strong vent in your kitchen, you may use your stove with a burner set to high. Place a large cast-iron grill pan over the heat and allow it to get hot. You can let the fire die slightly. If using a gas grill or stove, turn heat to medium.
• Put the potatoes and the sliced onions in a large bowl and toss gently with 2 tablespoons of the olive oil, and salt and pepper to taste. Working in batches, grill the potatoes cut-side down on the grill until they have developed a light char, approximately 2 to 3 minutes. Grill the onions until they are charred, approximately 4 to 6 minutes a side. Return potatoes and onions to bowl.
• For the dressing, combine the remaining olive oil, bacon fat, red-wine vinegar and chipotle in a small bowl and whisk to emulsify. Add salt and pepper to taste. Add the dressing to the potato-and-onion mixture and toss gently to combine. Let sit for 20 minutes to allow the flavors to penetrate the potatoes. Crumble bacon over the top.

Steps:

• Bring potatoes, 1/4 cup kosher salt, and 8 cups 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.
• Whisk egg yolk, lemon juice, and a pinch of sea salt in a small bowl. Gradually whisk in 1/2 cup olive oil until mayonnaise forms. Stir in shallot and tarragon. Season to taste with pepper. DO AHEAD: Can be made 4 hours ahead. Cover and chill.
• Heat remaining 1 1/2 teaspoons olive oil in a small skillet over medium-high heat. Add capers and fry, stirring often, until crisp and golden, 2-3 minutes. Using a slotted spoon, transfer capers to paper towels to drain. DO AHEAD: Can be made 4 hours ahead. Let stand at room temperature.
• Pour vegetable oil into a large pot to a depth of 2". Attach a deep-fry thermometer to side of pot. Heat oil over medium heat until thermometer registers 375°F. Working in batches, fry potatoes until crisp and dark golden brown, 3-4 minutes. Drain on paper towels. Season lightly with sea salt.
• Arrange warm potatoes on a platter, cut side up. Spoon some mayonnaise over each; sprinkle with capers.
