Why it works: Cream and sugar 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 ↓

Add the mixture to the well-beaten eggs.
Pour a pint of milk, heated to boiling, over this mixture.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set and thicken the custard base, giving the ice cream a rich, smooth body.
- Arrowroot
- Thickens the custard base so the ice cream stays smooth and resists icy crystals.
- Cream
- Adds fat, which makes the ice cream creamy and tender on the tongue.
- Sugar
- Adds sweetness and lowers the freezing point, keeping the ice cream soft enough to scoop.
- Coffee
- Provides the main coffee flavour and aroma throughout the frozen base.
- Milk
- Adds moisture and dilutes the custard, helping it cook to a smooth, pourable base.
The step that matters
Add the coffee when the mixture is partly frozen. Adding coffee at this point lets it mix in evenly while the base is still slushy. Beating breaks up ice crystals, so the coffee flavour spreads through and the texture stays smooth rather than grainy.
Swap the arrowroot
How well each one fits the dish's main ingredients (cream, milk, egg, coffee, sugar):
- Potatofits better
- Asparagusfits better
- Capsicumfits better
- Arrowrootthe original
Fit is the average pairing score against cream, milk, egg, coffee, sugar. Candidates are from the same food group and used in at least 100 recipes.
