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.
Stir the flour mixture into the boiling milk.
Let the mixture boil for one minute.
Remove from heat and set aside to cool.
Assemble and bake
Beat the eggs.
Add the beaten eggs to the cooled milk along with sugar and your chosen flavoring.
Line pie plates with pastry.
Pour the mixture into the lined pie plates.
Bake in a moderate oven at 350°F (175°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the milk into a smooth, stable custard base when boiled.
- Eggs
- Set the custard as they cook, giving it a firm, sliceable texture.
- Milk
- Forms the liquid body of the custard and becomes creamy as it sets.
The step that matters
Mixing the flour smoothly into the milk. Flour added to hot liquid can clump into lumps. Mixing it smooth with cold milk first lets the starch disperse evenly, so the boiled mixture thickens into a uniform custard.
“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.
