Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White stock
- Forms the liquid base of the sauce and carries the flavour.
- Cream or milk
- Adds richness and body to the sauce.
- Arrowroot
- Thickens the liquid as it heats, giving the sauce body.
The step that matters
Stirring in the dissolved arrowroot and cooking until thickened. Arrowroot must be dissolved in cold water first so it does not clump. Stirring constantly while the sauce heats keeps the starch evenly dispersed, so it thickens smoothly instead of forming lumps or a thin, uneven texture.
Swap the clove
How well each one fits the dish's main ingredients (parsley, cream, arrowroot):
- Capersfits better
- Nutmegfits better
- Tarragonfits better
- Clovethe original
Fit is the average pairing score against parsley, cream, arrowroot. Candidates are from the same food group and used in at least 100 recipes.
