Crispy Salt-and-Vinegar Potatoes
from http://www.bonappetit.com/

Cooking the potatoes in vinegar seasons them from within, and a final drizzle boosts the flavor.
2 pounds baby Yukon Gold potatoes, halved, quartered if large
1 cup plus 2 Tbsp. distilled white vinegar
1 tablespoon kosher salt, plus more
2 tablespoons unsalted butter
Freshly ground black pepper
2 tablespoons chopped fresh chives
Flaky sea salt (such as Maldon)
Combine potatoes, 1 cup vinegar, and 1 Tbsp. kosher salt in a medium saucepan; add water to cover by 1”. Bring to a boil, reduce heat, and simmer until potatoes are tender, 20–25 minutes; drain and pat dry.
Heat butter in a large skillet over medium-high heat. Add potatoes; season with kosher salt and pepper. Cook, tossing occasionally, until golden brown and crisp, 8–10 minutes. Drizzle with remaining 2 Tbsp. vinegar. Serve topped with chives and sea salt.
Alternatively, mix the potatoes with olive oil until generously coated. Evenly spread the potatoes out onto the prepared baking sheet. Bake for 25 minutes. After 25 minutes, broil the potatoes until crispy, stirring every five minutes to ensure that they don't burn. Allow them to crisp up to your liking — this might take anywhere from 5 to 15 minutes. Once they are crispy, remove them from the oven. Season with additional salt to taste. Sprinkle with chives.

Grilled Potato Slices with Salt and Vinegar
from https://www.marthastewart.com/
Simmering potatoes in vinegar imparts a pleasant tang reminiscent of salt-and-vinegar potato chips. Grilling, a healthier technique than frying, gives the potatoes a nice charred flavor. Source: Martha Stewart Living, June 2009
1 pound potatoes, preferably fingerling, cut lengthwise into 1/4-inch-thick slices
2 cups white vinegar
2 tablespoons extra-virgin olive oil
1/4 teaspoon freshly ground pepper
1 1/2 teaspoons coarse salt, plus more for sprinkling
Bring potatoes and vinegar to a boil in a medium saucepan (vinegar should cover potatoes). Reduce heat to medium-low, and simmer potatoes until just fork tender, about 5 minutes. Let potatoes cool in vinegar for 30 minutes. Drain well, and gently toss with oil, salt, and pepper.
Preheat grill to medium-high. Grill potatoes in a single layer until browned on both sides and cooked through, about 5 minutes per side. Sprinkle with salt before serving.
