Why it works: Sugar and cream 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 ↓
Banana Ice Cream
Ingredients
Directions
Make the custard
Make a steamed custard by combining milk, eggs, and sugar in a heatproof bowl over simmering water.
Stir until thickened, then cool the custard.
Finish and freeze
Once cold, mix in the cream and sliced bananas.
Freeze the mixture until solid.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as they cook, giving the base structure and body.
- Milk
- Forms the liquid base of the custard that the eggs thicken.
- Cream
- Adds fat and richness, producing a smooth, creamy texture.
- Sugar
- Adds sweetness and softens the frozen texture of the ice cream.
- Bananas
- Add banana flavor, sweetness, and body to the frozen mixture.
The step that matters
Thicken the custard gently. Egg proteins set at moderate heat. If the custard gets too hot or is heated too fast over the water, the eggs can curdle and turn grainy. Stir steadily until it coats the spoon, then cool it fully before adding the cream.
Swap the banana
How well each one fits the dish's main ingredients (milk, egg, sugar, cream):
- Vanillafits better
- Strawberryfits better
- Raspberryfits about as well
- Bananathe original
Fit is the average pairing score against milk, egg, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
