Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Caramelized browning builds a sweet, savory base for the sauce.
- Curry powder
- Blooming in fat releases aromatic compounds that give the dish its flavor.
- Milk
- Forms the liquid of the sauce and mellows the spice with creamy richness.
- Hard boiled eggs
- Provide the main protein and body, soaking up the sauce as they warm.
The step that matters
Cooking the onions until golden brown. Slow browning develops sweetness and depth through the Maillard reaction and caramelization. Pale or rushed onions leave the sauce flat and bitter-tasting.
Swap the onion
How well each one fits the dish's main ingredients (butter, milk, pepper, egg):
