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 ↓
Rose Custard
Ingredients
Directions
Make the custard
Heat the milk in a saucepan until it boils.
In a bowl, beat the eggs.
Gradually pour the hot milk into the eggs, stirring constantly.
Add the sugar and salt, and mix well.
Once cool, stir in the raspberry juice.
Cook and serve
Pour the mixture into a buttered mold.
Place the mold in a pan of boiling water and cook until set.
Let it cool, then serve with cream.

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
- Set the custard as they cook, giving it structure and a firm, sliceable texture.
- Milk
- Provides the liquid base and moisture that the eggs set into a creamy custard.
- Sugar
- Adds sweetness and balances the savoury richness of the eggs and milk.
- Raspberry juice
- Adds fruity flavour, colour and acidity to the custard.
The step that matters
Cook in a water bath until set. Eggs set through gentle, even heat. Cooking too hot or too long in the boiling water can cause the custard to curdle, weep or turn rubbery, so check for a firm set and remove it promptly.
Swap the raspberry
