Why it works: Butter and apple are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 8,706 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
Prepare
Heat clarified dripping or butter in a saucepan.
Peel and finely chop the onion.
Cut the cold meat into small pieces.
Peel, core, and finely chop the apple.
Brown the onion
Add the chopped onion to the hot dripping and brown it carefully. Shake the saucepan occasionally to prevent sticking.
Strain the browned onion and return the dripping to the saucepan.
Make the curry
Add the cold meat and brown on both sides.
Stir in curry powder, chopped apple, and salt.
Pour in cold water and add the browned onion.
Stir until it boils, then reduce heat and simmer uncovered for 30 minutes.
Remove the meat and serve on a hot dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cold meat scraps
- Provide the main protein, which browns in the dripping and becomes tender as it simmers.
- Apple
- Adds gentle sweetness and body that softens into the sauce as it cooks.
- Onion
- Browning builds savoury depth and sweetness that forms the base of the sauce.
- Curry powder
- Supplies the spice blend that gives the dish its characteristic aroma and flavour.
The step that matters
Browning the onion carefully. Onion that is scorched turns bitter and dark, while onion browned slowly develops sweetness and rich colour. Shaking the pan keeps the pieces from sticking and burning.
Swap the apple
How well each one fits the dish's main ingredients (meat, butter, onion):
- Avocadofits better
- Coconutfits better
- Grapefits about as well
- Applethe original
Fit is the average pairing score against meat, butter, onion. Candidates are from the same food group and used in at least 100 recipes.
