Gravlax sauce, also known as hovmästarsås, originated in Sweden as a traditional accompaniment to cured salmon (gravlax). The dill‑mustard sauce balances the rich, salty fish with bright, tangy flavors and is a staple at Swedish smörgåsbord gatherings.

In Norway and Denmark, the sauce may include a touch of honey or horseradish, while some Swedish families add a splash of aquavit. The core ingredients—dill, mustard, vinegar, and mayonnaise—remain consistent across the region.

It is typically served cold, spooned over thin slices of gravlax on rye bread or crispbread, often garnished with fresh dill and lemon wedges. It can also be used as a dip for boiled potatoes or vegetables.

Gravlax and its sauce are popular at midsummer celebrations, Christmas smörgåsbord, and Easter brunches. The dish is also a common feature at weddings and holiday feasts throughout Sweden.

The authentic sauce relies on dried dill, Dijon or stone‑ground mustard, white wine vinegar, sugar, and a good quality mayonnaise. While fresh dill can be used, the classic version prefers dried dill for its concentrated flavor.

Gravlax sauce pairs beautifully with gravlax itself, pickled herring, Swedish meatballs, and crisp rye or knäckebröd. It also works as a dip for boiled new potatoes and fresh cucumber slices.

Common errors include adding too much oil, which makes the sauce greasy, or not whisking enough, leaving lumps of dill. Over‑seasoning with vinegar can also make the sauce overly sharp; add it gradually and taste.

Dry dill disperses more evenly in the mayonnaise and provides a stronger, consistent flavor without adding extra moisture, which helps keep the sauce smooth and thick.

Yes, the sauce can be prepared up to a week in advance. Store it in an airtight container in the refrigerator and give it a quick stir before serving to recombine any settled oil.
