Preparation steps

    Pickled onions

    1. Heat apple cider vinegar, cane sugar, LINIE Aquavit, salt and spices in a pot.

    2. Add the sliced red onion rings and let it simmer for about 10 minutes.

    3. Remove the pot from the heat and let it cool until the next day.

    — At least 1 day later:


    1. Rinse the potatoes well and boil them in a large pot with plenty of salt until they are tender.

    2. Let them cool a bit before cutting them into bite-sized pieces.

    LINIE mayo

    1. Make LINIE mayo by mixing egg yolks, dijon mustard and LINIE Aquavit Original in a bowl.

    2. Whisk everything together while adding the oil in a thin stream and continue whisking until the mayo has a suitable consistency.

    3. Season with salt, pepper, lemon juice and LINIE Aquavit Original.

    4. When the mayo has the right consistency, add the chives and mix it around.

    Fried onions

    1. Toss the sliced Zittauer onion rings in flour, salt and pepper.

    2. Heat the oil in a pan and fry the onions until they are golden and crispy.

    3. Remove them from the heat and place them on a piece of kitchen towel to let the excess oil drain off.

    4. If you want a thicker coating, the process with flour can be repeated.

    5. Keep an eye on the heat to ensure that the onions turn golden and the oil does not get too hot.


    1. Spread your rye bread with your LINIE mayo and add the potatoes on top.

    2. Before serving, garnish with more mayo, pickled, and fried onions and plenty of watercress and freshly ground pepper.

Serve with a glass of LINIE and share a great story In addition to being a classic, high-quality aquavit, LINIE is also great for food pairing. What sets LINIE apart is its distinctive aging process. During maturation, it develops a natural sweetness and spiciness that makes it perfect for accompanying a variety of dishes. LINIE acts as a flavor enhancer, creating a harmonious balance between both food and aquavit.

As your guests indulge in this Danish classic, share the intriguing story of LINIE Aquavit's journey across the globe, matured in sherry oak casks as it crossed the equator twice. It's a tale that will add a touch of adventure to the dining experience.
