Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Arrowroot
- Thickens the custard as its starch swells and gels when heated.
- Eggs
- Set the custard through protein coagulation and add richness and body.
- Milk
- Forms the liquid base and gives the custard its creamy texture.
The step that matters
Pouring the boiling milk into the eggs. Adding the hot milk slowly while stirring constantly raises the egg temperature gradually. This lets the egg proteins thicken smoothly instead of curdling into lumps.
Swap the arrowroot
How well each one fits the dish's main ingredients (milk, egg):
- Asparagusfits better
- Potatofits better
- Capsicumfits better
- Arrowrootthe original
Fit is the average pairing score against milk, egg. Candidates are from the same food group and used in at least 100 recipes.
