Why it works: Milk and arrowroot work together. They rank in the top 18% of all ingredient pairs, and cooks put them together in 817 recipes. Both carry 2-methylbutyraldehyde, which smells malty, chocolate. The science ↓
Ice Cream with Milk
Ingredients
Directions
Cook the base
Boil the milk in a pot.
In a cup, mix the arrowroot or cornstarch with ½ cup of cold milk until smooth.
Stir the arrowroot mixture into the boiling milk.
Finish and cool
Remove from heat and stir in the eggs and sugar that have been beaten together.
Mix everything well and set aside to cool.

Milk and sugar barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the liquid base that the thickened custard is built on.
- Eggs
- Add richness and help the mixture set as it cools.
- Sugar
- Sweetens the base and softens the texture of the frozen result.
- Arrowroot or cornstarch
- Thickens the milk so the base holds body instead of running thin.
The step that matters
Add the eggs and sugar off the heat. Stirring the beaten eggs and sugar into milk that has been removed from the heat lets the eggs thicken gently. Adding them to a boiling liquid can scramble the eggs into lumps.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, egg, sugar):
- Sweet potatofits better
- Capsicumfits better
- Asparagusfits better
- Arrowrootthe original
Fit is the average pairing score against milk, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
