Why it works: Milk and coffee are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 2,202 recipes. Both carry 4-heptenal, which smells creamy, biscuit. The science ↓
Baked Coffee Custard
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Infuse the milk
Grind the coffee.
In a saucepan, combine the ground coffee and milk; bring to a boil.
Remove from heat and let steep for 15 minutes, covered.
Make the custard
In a bowl, break the eggs and beat until mixed.
Add about 3 tablespoons of sugar and beat well.
Bring the coffee and milk back to a boil and strain it into the bowl of eggs, stirring briskly.
Sweeten to taste.
Bake and serve
Prepare 12 small custard cups in a baking pan.
Strain the custard into the cups.
Fill the pan with boiling water to half the height of the custard cups.
Bake at 350°F (175°C) for 10 to 12 minutes, until just set; do not overbake.

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 tender, sliceable structure as they cook.
- Milk
- Forms the creamy liquid base and carries the coffee flavor.
- Ground coffee
- Infused into the milk to give the custard its coffee aroma and flavor.
- Sugar
- Adds sweetness and balances the bitterness of the coffee.
The step that matters
Bake until just set, do not overbake. Egg proteins set as the custard heats. Past that point they tighten further, squeezing out liquid and leaving the custard grainy and watery. Removing it while it still wobbles in the centre lets residual heat finish the set.
