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

What each ingredient does

Milk
Forms the liquid base that the cornstarch thickens into a sauce.
Cornstarch
Thickens the milk into a smooth sauce when cooked fully.
Egg whites
Whip into foam that lightens the sauce's texture.

The step that matters

Remove from heat before adding the beaten egg whites and extract.. Egg whites cook and set when hot, so adding them off the heat keeps them airy and foamy rather than scrambled or dense.

Swap the currant

The recipe marks currant as optional. How well each one fits the dish's main ingredients (milk, egg, butter):

  1. Vanillafits better
  2. Coconutfits better
  3. Figfits better
  4. Currantthe original

Fit is the average pairing score against milk, egg, butter. Candidates are from the same food group and used in at least 100 recipes.
