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 ↓
Custard Pudding
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Make the custard
In a bowl, stir the egg and sugar together.
Add the milk and nutmeg, and stir well.
Butter a small pie dish and pour in the custard mixture.
Place the dish in a larger dish filled with water.
Bake
Bake for about 20 minutes without moving the dish until the custard is set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Provides protein that sets the custard into a soft, firm texture as it heats.
- Milk
- Supplies liquid and moisture that gives the custard its smooth, creamy body.
- Sugar
- Adds sweetness and helps keep the custard tender.
- Butter
- Greases the dish so the set custard releases cleanly and adds richness.
The step that matters
Bake without moving the dish. Egg proteins set gently as the custard heats; jolting the dish before it firms can cause cracks or a grainy, uneven texture. The water bath keeps the heat gentle so the custard does not curdle or overcook at the edges.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, milk, sugar, butter):
- Cinnamonfits better
- Nutmegthe original
- Gingerfits less well
- Parsleyfits less well
Fit is the average pairing score against egg, milk, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
“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.
