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
Make small paper cases from buttered writing paper.
Place a small piece of butter in each case.
Add chopped parsley or onion, pepper, and salt.
Cook and serve
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 in the paper cases.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a soft, custard-like texture as they cook in the paper case.
- Butter
- Adds fat and richness, and keeps the egg from sticking to the paper.
- Seasoned bread crumbs
- Add a light crust and some browning on the surface of the egg.
The step that matters
Glaze the tops with a hot spoon. Egg whites set with heat, so the top stays runny until it is nearly done. A hot spoon finishes the surface gently, without overcooking the yolk underneath, which would turn it dry and rubbery.
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.
