Why it works: Milk and raspberry are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 1,014 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Burnt Custard
Ingredients
Directions
Make the custard
Boil the milk and let it cool.
Mix the cooled milk with the egg yolks and stir over low heat for a few minutes.
Sweeten the mixture to your taste.
Assemble and brown
Place slices of Savoy cake in the bottom of a deep dish and pour the custard over it.
Whip the egg whites until stiff and spread them lightly on top of the custard.
Sprinkle sugar over the egg whites and use a very hot iron to brown the top.
Garnish with raspberry marmalade or any preserved fruit.

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
- Egg yolks
- Thicken the custard and enrich it with fat and emulsifiers as they set over gentle heat.
- Egg whites
- Whipped to stiff foam, they form a light topping that browns on the surface.
- Milk
- Forms the liquid base of the custard, which sets as the egg proteins coagulate.
- Savoy cake
- Soaks up the custard, giving the dish a soft, absorbent base layer.
- Sugar
- Sweetens the custard and caramelizes on the egg white topping for browning.
The step that matters
Stirring the egg yolk and milk mixture over low heat. Egg yolks set into a thickened custard at moderate temperatures, but higher heat or prolonged cooking can curdle them into lumps. Gentle, constant stirring keeps the custard smooth.
Swap the raspberry

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