Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mild onions
- Break down into a pulp to form the body and sweet flavour of the sauce.
- Butter
- Cooks the onions gently and adds richness to the sauce.
- Veal gravy
- Provides the savoury meaty base and liquid for the sauce.
- Boiling cream
- Adds richness and a smoother, silkier texture to the finished sauce.
The step that matters
Stew the onions slowly over low heat. Low, gentle heat softens the onions until they break down into a pulp without browning or scorching, which keeps the sauce smooth and mild in flavour.
