Why it works: Sugar and egg are a kitchen classic. They rank in the top 21% of all ingredient pairs, and cooks put them together in 122,807 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Raspberry Custard
Ingredients
Directions
Make the fruit base
Mix the raspberries and red currants with 1 quart of water and cook for 5 to 10 minutes.
Strain the juice through a fine sieve or muslin.
Return the juice to the saucepan, add the sugar, and reheat until boiling.
Thicken the boiling juice with cornflour, then set aside to cool.
Make the custard
Beat the eggs and carefully add them to the cooled fruit juice.
Stir the mixture over low heat until it thickens, but do not let it boil.
Serve
Serve cold in custard glasses or over macaroons or sponge cakes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the juice into a custard as they set when gently heated.
- Raspberries
- Provide the main fruit flavour and colour of the custard.
- Red currants
- Add tart acidity that balances the sweetness of the fruit.
- Sugar
- Adds sweetness and balances the tartness of the fruit.
- Cornflour
- Thickens the boiling juice so it holds body before the eggs are added.
The step that matters
Stir the custard over low heat without boiling. Egg proteins set gently as they warm; if the mixture boils, they curdle and the custard turns grainy and loses its smooth texture.
Swap the red currant
How well each one fits the dish's main ingredients (sugar, egg):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- Red currantthe original
Fit is the average pairing score against sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
