Why it works: Pepper and parsley 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 ↓
Chinese Eggs
Ingredients
Directions
Prepare the eggs
Boil 6 eggs for 45 minutes, then remove shells and slice them.
Make the sauce
In a double boiler, melt 2 tablespoons of butter and whisk in 2 tablespoons of flour.
Add ½ cup of stock, ⅓ cup of milk, ½ teaspoon of salt, and ½ teaspoon of black pepper; stir until thickened.
Combine and serve
Gently fold in the sliced eggs and cover for a moment.
Dust with 1 tablespoon of chopped parsley and serve.

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
- Provide the main body of the dish, and their sliced form is folded into the sauce.
- Butter
- Adds richness and fat, carrying flavour into the roux.
- Flour
- Thickens the sauce when cooked with butter into a roux.
- Milk
- Adds creaminess and body to the sauce as it thickens.
The step that matters
Stir the sauce until thickened. Flour needs time over heat in the fat and liquid to swell and gelatinise fully; stopping early leaves a thin, floury sauce. Keep the heat gentle in the double boiler so the milk does not scorch or curdle.
Swap the parsley
How well each one fits the dish's main ingredients (egg, butter, flour, milk, pepper):
- Nutmegfits about as well
- Cinnamonfits about as well
- Parsleythe original
- Cardamomfits about as well
Fit is the average pairing score against egg, butter, flour, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
“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.
