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

What each ingredient does

Cream
Provides fat that makes the frozen ice cream rich and smooth.
Sugar
Adds sweetness and keeps the frozen texture softer.
Gelatin
Helps the mixture set and stabilises its texture when frozen.
Bananas
Supply the main banana flavour and body to the ice cream.
Eggs (in the method)
Thicken the custard and add richness in the milk version.

The step that matters

Dissolve the gelatin fully before straining. Gelatin must be completely dissolved in the hot cream and sugar mixture. Undissolved particles can leave a gritty or rubbery texture once the ice cream is frozen.

Swap the lemon

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

  1. Vanillafits better
  2. Strawberryfits better
  3. Pineapplefits better
  4. Lemonthe original

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