Why it works: Parsley and onion are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Baked Eggs in Cases
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Grease china or paper ramekin cases with butter.
Mix the chopped parsley and onion with the breadcrumbs.
Sprinkle some breadcrumb mixture into the cases.
Place the cases on a baking sheet.
Bake and serve
Break an egg into each case and cover with the remaining breadcrumb mixture.
Bake in the oven until the eggs are set but not hard, then serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set to a soft, custard-like texture as they cook, forming the body of the dish.
- Breadcrumbs
- Form a light crust that holds the eggs and absorbs moisture as they bake.
- Butter
- Greases the cases so the baked eggs release cleanly and gain a little richness.
The step that matters
Baking until the eggs are just set. Egg proteins set as they heat, and they keep firming after leaving the oven. Pulling the dish when the whites are set but the yolks still look soft keeps the texture tender rather than rubbery or hard.
Swap the onion
How well each one fits the dish's main ingredients (butter, parsley, egg):
- Shallotfits better
- Chivefits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against butter, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
