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

What each ingredient does

Egg yolks
Their proteins set on gentle heat, thickening the custard into a smooth, spoonable texture.
Milk
Forms the liquid base that carries the flavour and gives the custard its body.
Sugar
Adds sweetness and helps the beaten yolks become light and smooth.
Butter
Adds fat for richer flavour and a silkier mouthfeel.
Bananas
Add fruity sweetness and aroma that flavour the finished custard.

The step that matters

Cooking the custard until thickened. Egg yolks thicken as their proteins set with heat, but if the mixture gets too hot or cooks too fast, the proteins tighten and curdle. A double boiler applies gentle, even heat to prevent this.

Swap the banana

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

  1. Vanillafits better
  2. Figfits better
  3. Coconutfits about as well
  4. Bananathe original

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