Roast potatoes until browned on the bottom for 25 to 30 minutes.
  • Step 4 After 25 to 30 minutes of roasting, flip the potatoes over and continue roasting for about 15 more minutes until they are golden brown on the top. Be careful not to let the onions (or potatoes) burn.
  • Step 5 Prepare the sauce. Combine parsley, cilantro, chives, dill, horseradish, garlic and salt in a food processor. Process until finely chopped. Add sour cream, yogurt, lemon zest, lemon juice, coriander, sugar and cayenne. Mix until smooth
