We need:
1 large onion, diced
2 medium potatoes
Zest and juice of ½ lemon
2 smoked herring fillets, cut into medium pieces
½ cup black raisins
4 tbsp yogurt
½ cup fresh parsley, finely chopped
Salt
Freshly ground pepper
1
In a small pan (or saucepan), sauté the onion for 2–3 minutes with two tablespoons of water until it softens and the water evaporates. Set aside.
2
Boil the potatoes in salted water for 30–40 minutes until tender. Peel them, cut into medium pieces, and mash them with a fork or a spoon.
3
Place the herring, sautéed onions, freshly ground pepper, a little salt, lemon juice, and lemon zest into a blender and blend for 2 minutes until a thick paste forms. Remove from the blender, add the mashed potatoes, and mix with a wooden spoon for 3–4 minutes until well combined.
4
Wash and dry the blender bowl thoroughly and add the raisins, yogurt, and parsley. Blend well and add this mixture to the bowl with the herring mixture.
5
If you wish, you can mix the two mixtures together, or leave them as they are for a more decorative presentation.
6
Cover the bowl with plastic wrap and refrigerate the herring salad for 1 hour, until it sets and the flavors blend well.
