Wash potatoes and put them on a baking sheet. Poke each one 4-5 times with a fork. Brush them with a bit of olive oil, add a sprinkle of kosher salt, and bake for 50-60 minutes until a skewer slides in easily. Take them out and cool for 5 minutes.

Once they're cool enough to touch, take the skin off the potatoes and cut them into chunks about 1-inch big. Don't worry if they fall apart a bit. Throw everything in a big mixing bowl. While they're still warm, drizzle the apple cider vinegar over them and let them sit for 15-30 minutes until they cool down.
