Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Starch that swells and thickens the milk as it heats.
- Eggs
- Add richness and help the pudding set as it cooks.
- Butter
- Adds fat for a smoother, richer texture.
- Milk
- Forms the liquid base that the arrowroot thickens.
- Sugar
- Adds sweetness to the pudding.
The step that matters
Let the mixture boil until thick. Arrowroot starch only thickens fully once it reaches a boil, and stirring while it boils helps keep the mixture smooth rather than lumpy.
