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

What each ingredient does

Mixed fruit
Provides the main flavor and body of the soup once cooked and sifted.
Corn starch
Thickens the liquid into a smooth, lightly viscous soup as it cooks.
Lemon juice or orange juice
Adds acidity that brightens the sweetness of the fruit.

The step that matters

Thicken with corn starch. Corn starch must be heated in the liquid to swell and gelatinize; if undercooked it leaves a raw, chalky taste, and if added without enough stirring it can form lumps.

Swap the lemon

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

  1. Vanillafits better
  2. Apricotfits better
