Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Egg Salad
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the dressing
In a saucepan, combine cream, butter, parsley, and flour; cook until thick.
Assemble
Slice the hard boiled eggs.
Layer the sliced eggs in a dish, sprinkling bread crumbs over each layer.
Pour the cream dressing over the eggs.
Bake and serve
Bake in a 400°F (200°C) oven until brown.
Garnish with parsley and serve hot.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Form the bulk of the dish and set firm and tender when heated.
- Cream
- Adds richness and moisture to the dressing, keeping the eggs from drying out.
- Butter
- Adds fat and richness, and helps carry flavor through the dressing.
- Flour
- Thickens the cream dressing as its starch swells with heat.
The step that matters
Cook the cream dressing until thick. Flour only thickens fully when the mixture is cooked long enough for its starch to swell. If it is undercooked, the sauce stays thin and can taste raw and floury.

- Onionthe original
Fit is the average pairing score against egg, cream, butter, parsley, flour, pepper, vinegar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
