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.
