Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrow-root
- Thickens the milk into a smooth, set custard-like mixture as it cooks.
- Eggs
- Add structure and richness, helping the pudding set as it bakes.
- Powdered white sugar
- Sweetens the pudding and dissolves easily into the warm mixture.
The step that matters
Pour the boiling milk over the arrow-root mixture, stirring briskly. Arrow-root thickens when heated with liquid, so the milk must be hot and stirred constantly to prevent lumps and ensure even thickening.
Swap the potato
The recipe marks potato as optional. How well each one fits the dish's main ingredients (milk, sugar, egg, lemon):
- Asparagusfits better
- Arrowrootfits better
- Sweet potatofits better
- Potatothe original
Fit is the average pairing score against milk, sugar, egg, lemon. Candidates are from the same food group and used in at least 100 recipes.
