Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softened by boiling, it forms the body of the sauce and adds mild sweetness.
- Flour
- Thickens the cooking liquid into a paste-based sauce that coats the brains.
- Curry powder
- Supplies the spiced aroma and flavour that define the dish.
- Baking soda
- Raises the pan's alkalinity, helping the onion soften quickly during boiling.
- Tart apple
- Adds acidity that balances the richness of the brains and the sweetness of the onion.
The step that matters
Bring to a boil for a few moments. Flour thickens only when its starch granules heat in liquid and swell. Boiling briefly after adding the paste fully thickens the sauce, while overcooking can break it down and make it thin or pasty.
Swap the apple
How well each one fits the dish's main ingredients (onion, flour, pepper, rice):
- Avocadofits better
- Limefits better
- Mangofits better
- Applethe original
Fit is the average pairing score against onion, flour, pepper, rice. Candidates are from the same food group and used in at least 100 recipes.
