Why it works: Grape and corn work together. They rank in the top 14% of all ingredient pairs, and cooks put them together in 333 recipes. Both carry (e)-2-octenal, which smells fatty, green. The science ↓

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

What each ingredient does

Grape juice
Provides the main liquid, flavour and natural sweetness of the sauce.
Corn starch
Thickens the juice as it heats, giving the sauce body.

The step that matters

Adding the corn starch mixture to the boiling juice. Cornstarch must be fully smooth before it goes in, and the juice must be boiling. Starch granules swell and thicken on heating; adding lumpy or unmixed starch causes clumps that are hard to remove.

Swap the grape

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

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

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