Why it works: Pepper and onion are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Egg Timbale
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 the custard
Beat the eggs until they are frothy.
Add the milk, salt, pepper, and onion juice, and mix well.
Strain the mixture into buttered individual molds or popover cups.
Bake and serve
Place the molds in a baking dish filled with hot water.
Bake at 400°F (200°C) for about 20 minutes.
Turn out the timbales and serve with a cream sauce made from bread crumbs.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a delicate custard that holds the timbale's shape when baked.
- Milk
- Adds moisture and softness, keeping the custard tender rather than rubbery.
The step that matters
Bake in a water bath. Placing the molds in hot water surrounds them with gentle, even heat. This keeps the egg proteins from overheating, which would otherwise make the custard curdle, weep, or turn firm and grainy.
Swap the onion
How well each one fits the dish's main ingredients (egg, milk, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against egg, 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.
