Poach the trout

Make the mustard sauce

  1. In a bowl, mix 1 teaspoon of made mustard, ¼ teaspoon of salt, and ¼ teaspoon of pepper.

  2. Add 1 tablespoon of vinegar and mix well.

  3. Gradually add 6 tablespoons of salad oil while vigorously beating the mixture until thick and creamy.

  4. Optionally, whisk in 1 tablespoon of whipped cream for added softness.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salad oil
Forms an emulsion with the mustard, creating a thick, creamy sauce.
Made mustard
Acts as an emulsifier, helping oil and vinegar stay blended in the sauce.
White wine
Flavors the poaching liquid, adding acidity and aroma to the gently cooked fish.
Vinegar
Adds acidity to the poaching liquid and to the sauce, sharpening the flavor.
Whipped cream
Adds softness and richness to the finished mustard sauce.

The step that matters

Adding the oil to the mustard. Oil must be added slowly while beating vigorously so it disperses into tiny droplets. Adding it too fast can break the emulsion, leaving a thin, separated sauce instead of a thick, creamy one.

Swap the mustard

How well each one fits the dish's main ingredients (white wine, vinegar, lemon, pepper, cream):
