Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Provide the main body of the dish, held in the sauce once halved.
- Flour
- Thickens the stock into a smooth sauce as it cooks.
- Curry powder
- Adds the spiced aroma and flavour that defines the dish.
- Onion
- Softens into the sauce, adding savoury sweetness and body.
- Apple
- Softens as it cooks, adding mild sweetness that balances the curry spice.
- Stock
- Forms the liquid base that the flour thickens into the sauce.
The step that matters
Fry the onion and apple without browning. Gentle frying softens the onion and apple and releases their flavour without caramelising them. Browning would make the sauce taste bitter and darker than intended.
Swap the apple
How well each one fits the dish's main ingredients (egg, flour, onion):
- Avocadofits better
- Raisinfits better
- Pumpkinfits better
- Applethe original
Fit is the average pairing score against egg, flour, onion. Candidates are from the same food group and used in at least 100 recipes.
