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

What each ingredient does

Green bananas
Main fruit that forms the body of the preserve.
Sodium sulfite
Helps prevent the cut fruit from browning during soaking.
Sugar
Sweetens the syrup and helps preserve the fruit.
Citric acid
Adds acidity that brightens the flavor of the syrup.
Citrus peel infusion
Adds aromatic citrus flavor to the syrup.

The step that matters

Processing time by can size. Processing time must match the can size so heat fully penetrates the jars, keeping the fruit preserved and the seal intact.

Swap the orange

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

  1. Figfits better
  2. Pearfits better
  3. Strawberryfits better
  4. Orangethe original

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