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 slice them.
Grease a pie dish with butter and layer the sliced eggs inside.
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
Serve with 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, giving it substance and a firm, sliced structure.
- White sauce
- Supplies moisture and a creamy binding that holds the dish together.
- Egg yolks
- Enrich the sauce and help it thicken and set as it bakes.
- Tarragon
- Adds its distinctive aniseed-like aroma and flavour.
- Tarragon vinegar
- Adds a light acidity that brightens the rich sauce.
The step that matters
Mixing the yolks into the hot white sauce. If the sauce is too hot when the yolks go in, they can scramble instead of blending smoothly. Stirring steadily while adding the yolks helps keep the sauce smooth and lets it thicken evenly in the oven.
Swap the tarragon
How well each one fits the dish's main ingredients (egg, sauce, vinegar, butter):
- Tarragonthe original
- Capersfits about as well
- Parsleyfits less well
- Nutmegfits less well
Fit is the average pairing score against egg, sauce, vinegar, butter. Candidates are from the same food group and used in at least 100 recipes.
