Why it works: Arrowroot and vanilla match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 242 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Arrowroot
Ingredients
Directions
Mix the arrowroot with a little water in a basin to form a smooth paste.
Boil the milk in an enamelled saucepan.
Pour the hot milk onto the arrowroot paste, stirring continuously.
Return the mixture to the saucepan and stir over heat for 1-2 minutes until just about to boil.
Sweeten to taste and add your preferred flavouring.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the milk into a smooth, set pudding as its starch swells when heated.
- Milk
- Forms the liquid base and provides creaminess and body to the pudding.
The step that matters
Adding the hot milk to the arrowroot paste. Stirring continuously while pouring the hot milk prevents the starch from clumping into lumps. The mixture must then be heated just until it thickens, since arrowroot loses thickening power if it is boiled hard or for too long.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, sugar, vanilla):
- Arrowrootthe original
- Sweet potatofits about as well
- Capsicumfits less well
- Potatofits less well
Fit is the average pairing score against milk, sugar, vanilla. Candidates are from the same food group and used in at least 100 recipes.
