Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Coffee Puff
Ingredients
Directions
Make the coffee custard
Beat the egg thoroughly and mix in the sugar.
Combine cornstarch with a little milk and add to the egg mixture.
Prepare a strong cup of coffee and place it in a double boiler.
Stir the egg mixture into the hot coffee and let it boil until thickened.
Finish the puff
Once cooled, fold in the whipped cream, reserving some for serving on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Sets with heat to thicken the custard and gives it structure.
- Cornstarch
- Thickens the coffee mixture as it heats and holds the custard together.
- Whipped cream
- Adds airiness and a light, creamy texture to the cooled custard.
- Sugar
- Sweetens the custard and balances the bitterness of the coffee.
The step that matters
Stir the egg mixture into the hot coffee and let it boil until thickened. Egg proteins set as they heat, but if the mixture gets too hot or is not stirred, the eggs can scramble and turn lumpy. Stirring keeps the heat even while the cornstarch thickens the custard.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
