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
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard
Heat the milk to boiling and pour it over the beaten eggs.
Add the sugar and salt, then cool until warm.
Stir in the raspberry juice.
If the mixture is not colored enough, add a few drops of carmine.
Bake and serve
Pour the mixture into a buttered fancy mold.
Set the mold in a saucepan of boiling water.
Bake in the oven at 350°F (175°C) until firm.
Once cold, turn out and serve on small plates.

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
- Set and thicken the custard, giving it firm structure when baked.
- Milk
- Forms the liquid base of the custard and adds richness and softness.
- Sugar
- Adds sweetness and helps soften the set custard.
- Raspberry juice
- Adds fruit flavor, aroma and the pink color of the custard.
The step that matters
Bake in the oven at 350°F (175°C) until firm. Egg proteins set as they heat, so the custard must be cooked just until firm. Overbaking causes curdling and a grainy, weeping texture.
Swap the raspberry
How well each one fits the dish's main ingredients (milk, egg, sugar):

- 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.
