Cold sauces & condiments
Hovmästarsås
hovmästarsås · An emulsified cold Swedish condiment built on Dijon (often blended with coarse Swedish) mustard, neutral oil, white wine vinegar, sugar, and fresh dill. The name translates to 'head-waiter's sauce,' referencing the old practice of senior waiters whisking the sauce tableside over gravlax. Known outside Scandinavia largely through the IKEA food market.

The formula
1:2 mustard:oil (oil is twice the mustard by volume), balanced with sugar and vinegar
Whats4eats measures 1/4 cup Dijon to 1/2 cup neutral oil; sweetness and acidity are tuned to taste rather than measured precisely.
Identity
- Swedish cold mustard-dill emulsion
- Pronounced 'hohv-MEH-star-sohs'
- Traditional smörgåsbord accompaniment to gravlax
- Built tableside by whisking oil into a mustard-vinegar base
- Sweet-tangy profile with pronounced dill character
- Closely related to French-style mustard emulsions in technique
Ingredients
| Base | Dijon mustard (often blended with coarse Swedish senap per ICA) | Forms the emulsion backbone; avoid bright yellow American-style mustard. |
| Fat | Neutral vegetable oil | Slowly whisked in to build a stable emulsion; the oil volume is roughly double the mustard. |
| Acid | White or red wine vinegar | Sharpens and lightens the sauce; brightens the dill. |
| Sweetener | Granulated sugar (or honey) | Balances mustard heat and vinegar acidity — essential to the sauce's character. |
| Flavor | Fresh dill, finely chopped | Defines the sauce; parsley is not an acceptable substitute. |
| Seasoning | Salt | Fine sea salt preferred; pulls flavors together. |
| Seasoning | White or black pepper | Lightly used; should not compete with the dill. |
Method
- 1Whisk Dijon mustard, vinegar, sugar, salt, and pepper in a bowl until smooth and the sugar dissolves.Creates a homogenous flavor base and ensures the sugar is dissolved before any fat is introduced, preventing graininess.
- 2Add oil drop by drop at the start, whisking continuously, then stream in the rest once a stable emulsion begins to form.Slow incorporation allows the mustard to emulsify the oil; adding oil too quickly causes the sauce to break.
- 3Whisk until the sauce is thick, glossy, and pale yellow with no surface oil pooling.A proper emulsion coats the back of a spoon and holds the suspended oil droplets.
- 4Fold in the finely chopped fresh dill and adjust seasoning with additional salt, sugar, or vinegar.Dill releases its oils best when added off-heat and at the end, preserving its bright aroma.
- 5Chill thoroughly before serving, ideally at least 30 minutes.Cold service thickens the emulsion further and lets the sweet-tangy-dill balance meld.
Techniques that matter
Slow emulsion by whisking
Mustard contains mucilage and crushed seed solids that stabilize oil-in-water emulsions; adding the oil gradually keeps droplets small and the sauce from breaking.
Tableside whisking (traditional)
Historically prepared by the head waiter (hovmästare) over cured salmon to guarantee freshness and demonstrate craft.
Finishing with fresh herbs off-whisk
Preserves the volatile oils in dill that would dissipate under continuous agitation or heat.
Variations & derivatives
Half Dijon, half coarse Swedish mustardSweden (Buffé/ICA tradition)
Adds texture and a more rustic, grainier bite than Dijon alone.
Red wine vinegar versionLyckasmedmat.se home recipe
Slightly fruitier and rounder acidity than the white-wine classic.
Honey-sweetenedModern Swedish home kitchens
Substitute honey for granulated sugar for a smoother, floral sweetness; reduce by one-third as honey is sweeter than sugar by volume.
Smoked-fish variant with extra dillCoastal Swedish households
Increases dill to 3–4 tablespoons and adds a squeeze of lemon for sharper fish accompaniments.
Used in these dishes
Substitutions
- Dijon mustard → Coarse Swedish senap — Use 100% Swedish mustard for a more traditional, grainier texture; blend half-and-half for balance.
- White wine vinegar → Red wine vinegar — Flavor shifts slightly fruitier; pairs better with darker cured salmon.
- Granulated sugar → Honey — Reduces volume by one-third; gives a smoother sweetness.
- Neutral vegetable oil → Light olive oil — Only if not overly peppery; extra-virgin will overpower the dill.changes result
- Fresh dill → Dried dill — Use one-third the volume; the bright, anise-like top note will be muted.changes result
Troubleshooting
Sauce breaks and oil pools on the surface
Oil was added too quickly or the mustard base was too cold/separated → Start a fresh spoonful of mustard in a clean bowl and whisk the broken sauce in drop by drop, as you would a failed mayonnaise.
Sauce is too sharp and bitter
Insufficient sugar or too much vinegar → Whisk in additional sugar (or honey) a pinch at a time until the sweet-tangy balance lands.
Sauce is too thin and watery
Too much vinegar or insufficient mustard for the volume of oil → Whisk in more mustard to tighten the emulsion, or chill — it will firm slightly when cold.
Dill flavor is flat or grassy
Dill was chopped too early, bruised, or overheated → Stir in freshly chopped dill just before serving and keep the sauce cold.
