Why it works: Onion and rice are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 10,433 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Curried Eggs
Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the curry base
Melt the butter in a pan and fry the chopped onion without browning it.
Add the curry powder and lemon juice, and fry gently for a minute.
Stir in the flour and cook for another minute.
Simmer the curry
Add the stock and chopped apple, stir until boiling, then simmer gently for 30 minutes with the lid on, stirring occasionally.
Finish and serve
Warm half of the egg pieces in the curry mixture until hot.
Pour the curry mixture onto a serving dish and arrange the remaining egg pieces around it.
Serve with boiled rice on the side.
Optionally, place the dish in a 400°F (200°C) oven for 2-3 minutes to heat through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softened without browning, it builds a sweet, mild base for the sauce.
- Curry powder
- Blooms in the fat to release the spice aroma that defines the dish.
- Flour
- Cooked into the fat, it thickens the stock into a smooth sauce.
- Stock
- Forms the liquid of the sauce and carries the flavour through the simmer.
- Apple
- Softens during simmering, adding body and a gentle sweetness that balances the spice.
- Eggs
- Add a firm, mild texture and body to the finished curry.
The step that matters
Stirring the stock into the flour mixture until boiling. Flour added to hot fat must be smoothed in before the liquid goes in; stirring while the stock heats keeps starch dispersed so the sauce thickens without lumps.
