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 ↓
Chocolate Custard
Ingredients
Directions
Prepare the custard
Prepare a soft custard by heating the milk and mixing in the yolks of five eggs.
Dissolve the chocolate in ½ cup of warm milk and heat it to boiling point.
Sweeten the chocolate mixture with brown sugar. Add vanilla extract.
Finish and serve
Pour the chocolate mixture into a dish.
Cover with the beaten egg white mixed with a little sugar. Brown the top slightly in the oven.
Serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the custard and add richness as they set when gently heated.
- Egg white
- Beaten and sweetened, it forms a light topping that browns in the oven.
- Milk
- Forms the liquid base of the custard, giving it a smooth, creamy body.
- Baker's chocolate
- Provides the chocolate flavour and, once dissolved, the dark colour of the custard.
- White sugar
- Sweetens the custard and helps balance the bitterness of the chocolate.
The step that matters
Heating the egg yolk custard. Egg yolks thicken only up to a point. If the custard is heated too fast or too hot, the proteins curdle and the texture turns grainy. Gentle, steady heat keeps it smooth and lets it thicken evenly.
