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 ↓
Eggs in Cases
Ingredients
Directions
Prepare the cases
Make small paper cases from buttered writing paper.
Place a small piece of butter in each case, then add a little chopped parsley or onion, pepper, and salt.
Cook
Place the cases on a gridiron over moderate heat.
When the butter melts, break a fresh egg into each case.
Sprinkle seasoned bread crumbs on top.
When nearly done, glaze the tops with a hot spoon.
Serve
Serve in the paper cases.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fresh eggs
- Set into a soft custard-like texture as they cook in the paper cases.
- Seasoned bread crumbs
- Form a crisp, lightly browned topping over the eggs.
- Small piece of butter
- Melts to coat the case and add richness and moisture to the eggs.
- Chopped parsley or onion
- Adds aroma and savory flavour to the eggs.
The step that matters
Glazing the tops with a hot spoon. Egg proteins set as they heat, so the whites must be firm before glazing; a hot spoon sets the surface and browns it lightly without overcooking the yolks. Timing near the end of cooking prevents runny whites or rubbery yolks.
Swap the parsley
How well each one fits the dish's main ingredients (butter, pepper, egg, bread):
- Parsleythe original
- Nutmegfits about as well
- Sagefits less well
- Tarragonfits less well
Fit is the average pairing score against butter, pepper, egg, bread. Candidates are from the same food group and used in at least 100 recipes.
