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 and a yellow color.
- Milk
- Forms the liquid base of the custard.
- Cornstarch
- Thickens the custard as it heats, giving it body.
- Egg whites
- Whipped into stiff peaks to form the airy meringue topping.
- Bananas
- Provide the fruit base and their own sweetness and flavor under the custard.
The step that matters
Stir the custard over heat until thick. Egg yolks can curdle or scramble if overheated, and cornstarch needs to reach a boil to reach full thickness. A double boiler and steady stirring keep the custard smooth.
Swap the walnut
How well each one fits the dish's main ingredients (milk, sugar, egg, butter, vanilla, banana):
- Almondfits better
