Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour or egg yolks
- Thickens the sauce as the starch or egg proteins set with gentle heat.
- Lemon slices
- Adds sharp acidity and citrus aroma to the stock.
- Soup stock
- Forms the liquid base that carries the other flavours.
The step that matters
Thicken the sauce. Flour or egg yolks thicken only as heat rises gently; if the sauce boils hard after adding egg yolks, they can scramble and turn grainy, and flour left unheated keeps a raw starchy taste.
Swap the nutmeg
How well each one fits the dish's main ingredients (lemon, sugar, parsley, pepper, flour):
- Marjoramfits better
- Cardamomfits about as well
- Thymefits about as well
- Nutmegthe original
Fit is the average pairing score against lemon, sugar, parsley, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
