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 oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Beat the egg slightly and add the milk, saccharin, salt, and vanilla or nutmeg.
Strain the mixture and pour it into a custard cup.
Bake
Bake in a 350°F (175°C) oven until firm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Its proteins set as they heat, turning the liquid mixture into a soft, sliceable custard.
- Milk
- Forms the liquid base that the egg thickens, giving the custard its creamy moisture.
- Saccharin
- Provides sweetness without sugar, balancing the savory bite of the egg.
The step that matters
Bake only until firm. Egg proteins set at moderate heat. Overbaking squeezes water out of the custard, making it grainy, weepy, or curdled, while underbaking leaves it runny in the centre.
