Why it works: Tarragon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,563 recipes. Both carry estragole, which smells anise, licorice. The science ↓

Ingredients
Directions
Make the sauce
In a small saucepan, melt the butter until very dark, almost black.
Quickly add the tarragon vinegar and cook for a moment longer.

Bake in the oven until the whites are set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a delicate structure as the whites cook, forming the body of the dish.
- Butter
- Browns and turns nutty in the pan, giving the sauce its deep, toasty flavor.
- Tarragon vinegar
- Adds sharp acidity that cuts the richness of the browned butter.
The step that matters
Melt the butter until very dark. Butter solids brown as its water evaporates and its milk proteins caramelize. Stopping too early leaves a pale, flat sauce, while going past dark brown turns it bitter. Watch closely and add the vinegar quickly to halt the browning.
Swap the parsley
How well each one fits the dish's main ingredients (butter, tarragon, vinegar, egg):
- Parsleythe original
- Capersfits about as well
- Dillfits about as well
- Thymefits less well
Fit is the average pairing score against butter, tarragon, vinegar, egg. Candidates are from the same food group and used in at least 100 recipes.
