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 body, sweetness and fruit flavor of the soup once cooked and mashed.
Corn starch
Thickens the liquid as it heats, giving the soup a lightly thickened body.
Sugar
Sweetens the soup and balances the tartness of the fruit.
Lemon juice or orange juice
Adds acidity and brightens the fruit flavor.

The step that matters

Thicken the soup a little with corn starch. Corn starch must be heated in liquid to swell and thicken. Adding too much leaves the soup pasty or gluey, while too little leaves it thin, so add it gradually and keep the soup warm enough for the starch to set.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (plum, cherry, pineapple, peach, corn, sugar):

  2. Apricotfits better

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