Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Baked Custard
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.
Make the custard
Boil the milk and let it cool slightly.
Add the sugar, eggs, and flavoring to the milk.
Bake
Pour the mixture into a pudding dish.
Bake in a 300°F (150°C) oven until set, about 30-40 minutes.
Check doneness by inserting a spoon handle; if the milk does not follow, the custard is set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Proteins set into a firm, sliceable custard as they heat and coagulate.
- Milk
- Provides the liquid base that gives the custard its creamy, moist texture.
- Sugar
- Sweetens the custard and slightly softens its set texture.
The step that matters
Baking until just set. Egg proteins coagulate as the custard heats. Removing it once the center is just set keeps it smooth; overbaking squeezes out liquid and makes it grainy or watery.
“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.
