Why it works: Coffee and chocolate match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 1,497 recipes mention both. Both carry 2,3-butanedione, which smells buttery, creamy. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Chocolate ice cream and macaroon cream
Bring the cream to a boil.
Thoroughly mix the bitter chocolate in until dissolved.
Add one and a half pounds of sugar.
Let cool and add the yolks of six eggs, well beaten.
Season with a small quantity of vanilla extract.
Let the milk come to a boil.
Add the yolks of two eggs, one teacup of sugar, and two tablespoons of corn starch, well creamed together.
Stir briskly until it thickens.
When partly cool, add the whites beaten to a froth.
When cool, add one quart of cream, a little sherry wine or vanilla, and one or two dozen macaroons, rolled fine. Freeze.
Orange cream
Cover the gelatine with cold water and let soak half an hour.
Whip the cream.
When the milk boils, dissolve the gelatine into it.
Beat the eggs and sugar together and strain the milk and gelatine into them.
Make the boiler clean, put the mixture in, and stir over fire two minutes.
Turn out to cool.
When cold, add the juice of the oranges (after straining).
Place this basin in a pan of cracked ice and stir constantly until it thickens.
Add the whipped cream and stir until well mixed.
Spanish cream
Heat the boiled coffee, milk and gelatine in a double boiler.
Add one-third cup sugar, salt, and three yolks of eggs beaten together.
Stir and cook until slightly thickened.
When cooled a little, add the beaten whites of eggs and one teaspoonful of vanilla.

Sugar and vanilla share little aroma chemistry, yet 35,031 recipes mention both: they likely work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custards as they heat, and whites add lightness to the creams.
- Gelatine
- Sets the cooled cream mixtures so they hold their shape when chilled.
- Corn starch
- Thickens the custard base so it becomes smooth and spoonable as it heats.
- Cream
- Adds richness and body, and whipped cream adds airy softness to the orange cream.
- Sugar
- Sweetens the custards and helps balance the flavour of the chocolate and oranges.
- Bitter chocolate
- Provides deep chocolate flavour and colour to the ice cream base.
The step that matters
Stirring the egg custard over heat. Egg yolks thicken as they warm, but if they get too hot they scramble and curdle. Keep the heat moderate and stir steadily until it just thickens.
