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

What each ingredient does

Orange juice
Provides the main liquid and citrus flavor of the sauce.
Lemon juice
Adds acidity that brightens the sweetness of the sauce.
Corn starch
Thickens the sauce as its granules swell when heated.
Sugar
Adds sweetness and body to the syrup.

The step that matters

Cooking until it thickens. Cornstarch only thickens once the mixture is hot enough for its granules to swell. Stopping too early leaves the sauce thin, so cook until it visibly thickens while stirring to prevent scorching and lumps.

Swap the lemon

How well each one fits the dish's main ingredients (orange, corn, sugar):

  1. Vanillafits better

  3. Limefits about as well
  4. Figfits about as well

Fit is the average pairing score against orange, corn, sugar. Candidates are from the same food group and used in at least 100 recipes.
