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 liquid into a smooth, glossy pudding as its starch gelatinises with heat.
Sugar
Adds sweetness and balances the flavour of the milk.
Milk
Adds richness and body, giving the pudding a creamy mouthfeel.

The step that matters

Mixing the arrowroot with cold water first. Arrowroot starch clumps when it meets hot liquid directly. Mixing it into a smooth cold slurry first lets the starch disperse evenly, so it thickens the pudding without lumps.

Swap the arrowroot

How well each one fits the dish's main ingredients (sugar, milk):

  1. Sweet potatofits better
  2. Capsicumfits better
  3. Potatofits better
  4. Arrowrootthe original

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