Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Rice flour
Thickens the sauce as its starch swells and sets when heated and boiled.
Milk or cream
Adds richness and body, giving the sauce a smooth, creamy texture.
White stock
Forms the liquid base and adds savory flavor to the sauce.
Cooked white fish
Provides the main protein and flesh of the dish.
Lemon juice
Adds acidity that brightens the flavor of the sauce and fish.

The step that matters

Boil the sauce for five minutes. Starch from the rice flour only thickens fully once the mixture reaches a boil and is held there. Stopping early leaves the sauce thin and can leave a raw, floury taste.

Swap the lemon

How well each one fits the dish's main ingredients (rice, flour, milk, fish, pepper):

  1. Lemonthe original
  2. Coconutfits about as well
  3. Limefits less well
  4. Raisinfits less well

Fit is the average pairing score against rice, flour, milk, fish, pepper. Candidates are from the same food group and used in at least 100 recipes.
