Why it works: Flour and milk 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 it cool.
Assemble and bake
Beat the eggs, then add them to the cooled milk along with the sugar and flavoring.
Line pie plates with pastry, pour in the mixture, and bake in a moderate oven at 350°F (175°C) until set.

Flour and milk 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
- Eggs
- Set the custard as they cook, giving it body and a firm, sliceable texture.
- Flour
- Thickens the milk into a smooth base so the custard holds its shape.
- Milk
- Forms the liquid body of the custard and carries the flavor.
The step that matters
Let the milk boil with the flour mixture for 1 minute. Flour starch only thickens fully once it has been heated to a boil, so the base must cook briefly before it cools. Otherwise the starch stays raw and the base can stay thin or taste floury.
