Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Vanilla Ice Cream
Ingredients
Directions
Make the custard base
Mix the egg yolk and Lyle's Golden Syrup together in a bowl.
Add the milk, cream (if using), lemon juice, and vanilla essence to the mixture.
Heat the mixture in a double boiler or a jug in hot water, stirring constantly until warm.
Strain the mixture through a sieve and let it cool.
Freeze
To freeze, place the mixture in a clean smaller tin, then put this tin inside a larger one.
Pack the space between the tins with broken ice and freezing salt.
Cover and roll the tins back and forth on the floor for 20 to 30 minutes, shaking occasionally.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Adds richness and helps emulsify the mixture into a smooth, creamy base.
- Milk
- Forms the liquid base of the ice cream, carrying flavour and setting into a soft texture.
- Cream
- Adds fat, which makes the frozen ice cream smoother and less icy.
- Lyle's golden syrup
- Adds sweetness and keeps the frozen texture softer by limiting large ice crystals.
The step that matters
Freezing with ice and salt. Salt lowers the melting point of the ice, making it colder than ice alone. Rolling keeps the mixture moving so ice crystals stay small and the texture stays smooth.
Swap the lemon
How well each one fits the dish's main ingredients (milk, cream, egg, vanilla, syrup):

Fit is the average pairing score against milk, cream, egg, vanilla, syrup. Candidates are from the same food group and used in at least 100 recipes.
