Why it works: Coffee and milk 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 ↓

Ingredients
Directions
Make the infusion
In a saucepan, pour boiling milk over ground coffee and cover.
Let it cool nearly to room temperature, then strain through a fine cloth.
Make the custard
Mix in powdered sugar and salt.
Stir in the beaten egg yolks until well combined.
Heat gently until it begins to thicken, then strain again through a fine cloth.
Add the dissolved isinglass and mix well.
Set and serve
Grease a mold with sweet almond oil and pour the mixture in.
Set the mold in ice until firm.

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 on gentle heating and enrich it with fat for a smooth, creamy texture.
- Milk
- Forms the liquid base that carries the coffee flavour and sets into a creamy body.
- Isinglass
- Gelatin-like protein that helps the custard set firm when chilled.
- Ground coffee
- Provides the main coffee aroma and flavour when steeped in the hot milk.
- Powdered sugar
- Adds sweetness that balances the bitterness of the coffee.
The step that matters
Heat gently until it begins to thicken. Egg yolks set when heated, so too much heat can scramble them into lumps. Heating slowly and stirring keeps the custard smooth and lets it thicken evenly.
Swap the almond
How well each one fits the dish's main ingredients (coffee, milk, sugar, egg):
- Cocoafits better
- Hazelnutfits about as well
- Pecansfits about as well
- Almondthe original
Fit is the average pairing score against coffee, milk, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
