Why it works: Tarragon and mustard match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 901 recipes. Both carry methyleugenol, which smells clove, spice. The science ↓
Dutch Sauce
Ingredients
Directions
Melt the butter in a basin.
Add the cream, egg yolks, tarragon vinegar, pepper, salt, and mustard.
Place the basin in a pan of boiling water on the stove.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify and thicken the sauce as they set with gentle heat.
- Butter
- Adds richness and fat that gives the sauce a smooth, silky body.
- Cream
- Adds moisture and softness, diluting the yolks so the sauce stays smooth.
- Tarragon vinegar
- Adds acidity that brightens the rich sauce and sharpens its flavour.
The step that matters
Beat over gentle heat until thickened. Egg yolks thicken when warmed slowly over gentle, indirect heat. Too much heat scrambles them, causing the sauce to curdle, which is why the basin sits over boiling water and the mixture must be beaten constantly.
Swap the mustard
How well each one fits the dish's main ingredients (butter, cream, egg, tarragon, vinegar, pepper):
