Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they set gently with the warm milk.
- Cream
- Adds fat and richness, giving the ice cream a smooth, creamy texture.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream softer.
- Bananas
- Add banana flavour and body once mashed into the cooled base.
- Milk
- Forms the liquid base that the yolks thicken into a custard.
The step that matters
Add the beaten yolks and sugar to the scalded milk, stirring until it thickens. Egg yolks can scramble if added to hot milk too quickly or left over heat. Stirring steadily while adding them thickens the custard smoothly instead of curdling it.
Swap the banana
How well each one fits the dish's main ingredients (cream, milk, sugar, egg):
- Vanillafits better
- Strawberryfits better
- Raspberryfits about as well
- Bananathe original
Fit is the average pairing score against cream, milk, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
