Why it works: Syrup and cream are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 1,964 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Vanilla Parfait
Ingredients
Directions
Make the custard
Beat the yolks of the eggs until light.
Add the syrup and place the mixture over low heat, stirring constantly until it thickens enough to coat the back of a spoon.
Transfer the mixture to a bowl and beat with a whisk until cold and light.
Add the vanilla and mix well.
Assemble and freeze
Whip the cream to stiff peaks, ensuring no liquid drains from it, and gently fold it into the custard.
Pour the mixture into a 3‑pint mold.
Pack the mold in ice and salt for 4 hours.

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 as they set on gentle heat, giving a rich, smooth body.
- Syrup
- Sweetens the parfait and helps keep it soft rather than rock-hard when frozen.
- Heavy cream
- Whipped into the custard to add air and a light, creamy texture.
The step that matters
Cooking the custard over low heat. Egg yolks scramble if they get too hot. Cooking gently while stirring constantly lets them thicken smoothly into a custard that coats a spoon.
