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 let it cool.
Make the custard
In a bowl, blend the sugar with the sifted flour.
Add the eggs to the cooled milk and mix well.
Stir in the flour and sugar mixture, and add salt and butter if desired.
Pour the mixture into a well-buttered dish.
Bake
Bake in the oven until set, being careful not to overcook.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Coagulate when heated, giving the custard its set structure.
- Milk
- Forms the liquid base and adds richness and a smooth texture.
- Flour
- Thickens the mixture and helps keep the custard smooth.
The step that matters
Bake in the oven until set, being careful not to overcook.. Egg proteins set as they heat. Once they set too far, they tighten and squeeze out liquid, so the custard turns grainy 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.
