Sauce: Lemon juice → Sunflower oil
  • The plate is identical — herring, boiled potatoes, onion rings, dill. The only decision is what you pour over it.
  • Two tablespoons of sunflower oil are about 30 g of mostly fat—more calories than the potatoes underneath. That brings the totals to 144 versus about 92 kcal per 100 g.
  • Lemon juice adds acidity for very few calories.
