Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Spanish onions
- Become very tender and sweet while staying pale, forming the body of the dish.
- Butter
- Fat that softens the onions gently and carries flavour.
- Flour
- Thickens the milk or cream into a smooth sauce as it cooks.
- Milk or cream
- Forms the liquid base that thickens into a creamy sauce.
- Hard-boiled eggs
- Add soft, tender texture and richness to the sauce.
The step that matters
Cook the onions without browning. Browned onions turn bitter and darken the sauce. Covered, gentle frying softens them and draws out their natural sweetness while keeping the colour pale.
Swap the onion
