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 ↓
Firm Custard
Ingredients
Directions
The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 325°F (165°C).
Make the custard
In a bowl, mix the milk, sugar, salt, and egg or egg yolks until well combined.
Add the flavoring of your choice and stir.
Pour the mixture into a baking dish.
Bake and test
Bake in the preheated oven until set, about 30-40 minutes.
To test, insert a silver knife in the center; it should come out clean.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Proteins set as the custard heats, giving it a firm, sliceable structure.
- Milk
- Provides the liquid base and moisture that the egg proteins set within.
- Sugar
- Adds sweetness and softens the set custard slightly.
The step that matters
Baking until just set. Egg proteins set as the custard heats, and overbaking squeezes out liquid and makes the custard grainy and watery. Testing with a knife shows when it is set but still moist.
“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.
