Why it works: Arrowroot and milk 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 ↓
Arrowroot
Ingredients
Directions
Mix the arrowroot smoothly with a little cold milk.
Boil the remainder of the milk and pour it on, stirring briskly.
Return to the saucepan and boil for about 5 minutes, stirring continuously.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Sugar and milk 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
- Arrowroot
- Thickens the milk as its starch swells and gelatinises when heated, giving the pudding its set.
- Milk
- Forms the liquid base that the arrowroot thickens, providing creamy body and flavour.
- Castor sugar
- Adds sweetness and is stirred in at the end, after thickening.
The step that matters
Stir continuously while the mixture boils. Arrowroot starch can clump and scorch on the base of the pan if left still. Constant stirring keeps the starch dispersed so it thickens evenly and smoothly as it gelatinises.
Swap the arrowroot
How well each one fits the dish's main ingredients (sugar, milk):

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