Why it works: Milk and cinnamon are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 12,655 recipes. Both carry cuminaldehyde, which smells Spicy, cumin. The science ↓
Milk Soup
Ingredients
Directions
Prepare the bread
Lay toasted bread slices in a tureen and pour hot milk over them.
Cover the tureen to let the bread soak.
Make the custard
Boil the milk with salt, cinnamon, and sugar.
Beat the egg yolks and gradually add them to the milk.
Stir the mixture over low heat until it thickens, then remove from heat immediately to prevent curdling.
Pour the thickened milk over the soaked bread in the tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that soaks the bread and becomes the thickened custard.
- Egg yolks
- Thicken the milk into a custard as their proteins set with gentle heat.
- Toasted bread
- Absorbs the hot milk and soft-soaks, giving the soup body and texture.
- Sugar
- Adds sweetness to the milk.
The step that matters
Stirring the milk and yolks over low heat. Egg yolk proteins set gradually as they warm. Too much heat, or too long, scrambles the yolks and makes the custard grainy or curdled, so the mixture must be stirred gently and removed from heat as soon as it thickens.
