Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Stock
- Forms the liquid base and carries the flavour of the other ingredients.
- Béchamel sauce
- Adds body and a creamy texture to the sauce.
- Onion
- Contributes savoury depth as it softens and flavours the stock.
- Ham
- Adds salty, meaty savour to the sauce.
- Vinegar
- Adds acidity that brightens the flavour and balances richness.
The step that matters
Adding the Béchamel and boiling. Béchamel is a flour-thickened dairy sauce that can separate, scorch or turn grainy if it is boiled hard or left too long on heat. Keep it at a gentle, controlled boil while stirring so the sauce stays smooth.
