Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soup stock
- Forms the liquid base that carries the other flavours.
- Lemon slices
- Adds acidity and bright citrus aroma to the sauce.
- Sugar
- Balances the sourness of the lemon with a touch of sweetness.
- Flour or egg yolks
- Thickens the liquid so it becomes a coating sauce.
The step that matters
Thickening the sauce. Egg yolks can curdle or scramble if they meet a boiling liquid directly. Flour needs to be cooked through or it tastes raw and clumps. Thickening gently, with the heat reduced, keeps the sauce smooth.
Swap the parsley
How well each one fits the dish's main ingredients (lemon, sugar, nutmeg, flour):
- Cinnamonfits better
- Cardamomfits better
- Marjoramfits better
- Parsleythe original
Fit is the average pairing score against lemon, sugar, nutmeg, flour. Candidates are from the same food group and used in at least 100 recipes.
