Ingredients
  

  • 3 pounds potatoes
  • 1 green apple
  • 1 red onion
  • 1 pickled gherkin
  • ½ cup mayonnaise
  • 1 cup sour cream or Turkish/greek yogurt
  • 2 tablespoon sweet strong mustard (kotisinappi)
  • ½ teaspoon black pepper
  • ½ teaspoon salt
  • ½ teaspoon sugar

On top

  • cup chopped spring onion or chives

Instructions
 

  • Wash an peel the potatoes and place them in a large pot with enough water to cover them. Bring to a boil over high heat and then reduce the heat to medium-low. Cook the potatoes until they are fork-tender, but not falling apart, about 30 minutes. Cook time depends on the size of potatoes. For small potatoes 15 minutes is enough. Drain and let cool for a few minutes.
  • Chop the red onion into small dices. Cut also the gherkin in small dices.
  • Wash and cut the apple (if using) into bite-size pieces. Add the apple, gherkin and red onion in a bowl.
  • Whisk together the mayonnaise, sour cream, sweet mustard, black pepper, salt, and sugar in a small bowl until well combined.
  • Once the potatoes have cooled, cut them into bite-size pieces and add them in the bowl.
  • Pour the dressing over the mixture and stir until everything is well coated. Taste and adjust the seasoning as needed.
  • Cover the bowl with plastic wrap and refrigerate for at least 1 hour before serving to allow the flavors to meld together.
  • Decorate with chopped spring onion or chives.

Notes

This potato salad can be made ahead of time and refrigerated for up to 2-3 days. If the salad seems dry after sitting in the fridge, add a bit more mayonnaise or yogurt/sour cream and stir to combine.
The salad gets a bit lighter and lower in calories if you use turkish yogurt or Finnish kermaviili instead of sour cream. 
Red onion can be replaced with leek or spring onion. 
Pickled gherkin can be replaced with pickled capers.
