Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Raspberry Custard
Ingredients
Directions
Make the custard
Combine milk and sugar in a saucepan, then set it over a pot of boiling water.
Mix corn starch with a little cold milk, then stir until it boils for 2 minutes.
Beat yolks with a spoonful of cold milk, then stir into the mixture, cooking until thickened but not boiling.
Remove from heat, stir in raspberry syrup.
Finish and serve
Beat egg whites with 1 tablespoon sugar until stiff, then fold into the mixture.
Pour into custard cups and serve warm or cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Yolks thicken the custard, and whites beaten stiff lighten its texture.
- Corn starch
- Starch thickens the milk as it heats and boils, giving the custard body.
- Rich sweet milk
- Forms the liquid base of the custard and gives it richness.
- Raspberry syrup
- Adds raspberry flavour and sweetness to the custard.
The step that matters
Cooking the yolks until thickened but not boiling. Egg yolks thicken as they heat, but if they boil they can curdle and turn grainy. Stirring gently and stopping at thickness keeps the custard smooth.
