Why it works: Pepper and tarragon match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 2,399 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Mayonnaise Sauce for Salmon
Ingredients
Directions
Prepare
Chill the salad oil in a bowl of ice water for 30 minutes.
In a quart saucepan set on crushed ice, add the egg yolks.
Sprinkle the pepper and salt over the yolks and stir them together.
Make the mayonnaise
Slowly drizzle the salad oil over the yolks while whisking rapidly.
Continue adding oil and whisking until the mixture thickens.

Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsify the oil into the mixture and thicken it into a rich, stable sauce.
- Salad oil
- Provides the fat that forms the body and richness of the mayonnaise.
The step that matters
Adding the oil slowly while whisking rapidly. Oil added too fast cannot be absorbed by the yolks, so the emulsion breaks and the sauce stays runny or separates. Slow drizzling with constant whisking lets tiny oil droplets disperse and be held in the yolk's lecithin-stabilised mixture.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, pepper, vinegar):
- Tarragonthe original
- Dillfits about as well
- Parsleyfits less well
- Allspicefits less well
Fit is the average pairing score against egg, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes.
