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 ↓

Ingredients
Directions
The book says “a slow oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Boil the milk and then let it cool.
Make the custard
In a bowl, blend the sugar with the sifted flour.
Add the eggs to the flour and sugar mixture, then gradually stir in the cooled milk.
If desired, add a small lump of butter for richness.
Bake
Pour the mixture into a well-buttered dish.
Bake in the oven until set, being careful not to overcook.

Flour and butter barely smell alike, yet cooks put them together in 124,287 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 firm up as they heat, giving the custard its structure.
- Milk
- Forms the liquid base that the eggs set into a smooth custard.
- Flour
- Thickens the mixture and helps it hold together as it sets.
The step that matters
Bake until set, without overcooking. Egg proteins coagulate as the custard heats. Removing it once just set keeps it smooth and tender. Overbaking squeezes out liquid and makes the custard grainy, watery or curdled.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
