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 ↓
Parmesan Custards
Ingredients
Directions
Make the custard
Beat the eggs in a bowl.
Add boiling milk, Parmesan, salt, pepper, and cayenne, stirring continuously to prevent the cheese from settling.
Pour the mixture into small buttered molds.
Place the molds in a saucepan with water reaching halfway up the sides.
Simmer gently until set.
Prepare the bread
Cut thin slices of bread and stamp out rounds slightly larger than the molds.
Heat butter in a frying pan and fry the bread until golden.
Assemble and serve
Place one custard on each bread round, top with grated cheese, and brown under a gas burner or in front of a fire.
Serve on lace paper, garnished with parsley or cress.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the custard into a firm, sliceable structure as they cook.
- Milk
- Provides the liquid base that gives the custard a soft, creamy texture.
- Butter
- Adds richness and helps the bread brown golden in the pan.
- Parmesan cheese
- Adds savoury flavour and salty depth to the custard.
The step that matters
Simmer gently until set. Egg custards turn grainy or watery if boiled hard, because the proteins tighten too fast and squeeze out liquid. Gentle heat in a water bath lets them set evenly and smoothly.
