Why it works: Milk and flour are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 78,219 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
French Custard Pudding
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard base
Boil the milk in a saucepan.
Mix the flour smoothly with a little cold milk.
Once the milk boils, stir in the flour mixture and let it boil for 1 minute.
Remove from heat and let cool.
Assemble and bake
Beat the eggs and add them to the cooled milk along with sugar and your chosen flavoring.
Line your pie plates with the pie crust.
Pour the custard mixture into the lined pie plates and bake in a moderate oven at 350°F (175°C) until set.

Milk and flour barely smell alike, yet cooks put them together in 78,219 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
- Milk
- Forms the liquid base of the custard and, once cooked, sets into a creamy body.
- Flour
- Thickens the milk into a smooth base that supports the custard's structure.
- Eggs
- Set during baking to give the custard its firm, sliceable texture.
- Sugar
- Adds sweetness and balances the flavor of the milk and eggs.
The step that matters
Let the milk-flour mixture boil for 1 minute. Flour starch only thickens fully when heated to a boil and held there briefly. Skipping this leaves a thin base that will not give the custard a proper body.
