Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the sauce and carries the flavours of the aromatics as they simmer.
- Flour
- Thickens the sauce with the butter, giving it body and a smooth texture.
- White stock
- Forms the liquid base of the sauce, providing most of its volume.
- Sherry
- Adds acidity and depth of flavour to the stewed liquid.
- Onion
- Softens during simmering and contributes sweetness and savoury body to the sauce.
- Lemon juice
- Adds acidity that brightens the finished sauce.
The step that matters
Thickening the sauce. Butter and flour must be cooked into a smooth paste before being stirred into the hot liquid, or lumps form. Stirring over heat until smooth lets the starch swell evenly and thicken the sauce.
