Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
A Finer Baked Custard
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the custard base
In a saucepan, gently boil the milk, salt, lemon rind, and sugar for 5 minutes.
Gradually stir the hot mixture into the beaten egg yolks and egg whites.
Strain the mixture and add the cream.
Let it cool, then flavor with brandy or ratafia.
Bake
Pour into small well-buttered cups and bake slowly at 300°F (150°C) for 10 to 12 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set as the custard bakes, giving it a firm yet tender body.
- Milk
- Forms the liquid base, and its proteins help the custard set gently.
- Cream
- Adds fat, making the custard richer and smoother on the palate.
- Sugar
- Sweetens the custard and softens the texture of the set custard.
- Lemon rind
- Its oils add a bright citrus aroma to the warm milk.
The step that matters
Bake slowly at a low temperature. Egg proteins coagulate under heat. Too hot or too long, the custard can overset, turn grainy, or weep liquid, so gentle heat keeps it silky.
Swap the lemon

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