Why it works: Tarragon and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,547 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Tarragon Eggs
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Boil the eggs for 7 minutes, then cut them into slices.
Butter a pie dish and lay the egg slices in it.
Make the sauce and bake
In a bowl, mix the hot white sauce with the egg yolks, tarragon, and tarragon vinegar.
Pour the mixture over the eggs in the pie dish.
Bake at 350°F (175°C) for 10 minutes.
Serve with fried croutons around the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Form the main body of the dish, holding its structure as sliced eggs.
- White sauce
- Provides a creamy, moist coating that binds the eggs together.
- Egg yolks
- Enrich the sauce and help it thicken and set when baked.
- Tarragon vinegar
- Adds a sharp acidity that brightens the rich sauce.
The step that matters
Mixing the yolks into the hot white sauce. Egg yolks thicken when heated, but if the sauce is too hot or stirred poorly, the yolks can scramble into lumps instead of forming a smooth, set custard-like sauce.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, sauce, vinegar):
- Tarragonthe original
- Capersfits about as well
- Dillfits less well
- Parsleyfits less well
Fit is the average pairing score against egg, sauce, vinegar. Candidates are from the same food group and used in at least 100 recipes.
