Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rich milk
- Forms the liquid base that thickens and moistens the toast.
- Butter
- Adds fat for richness and a smoother mouthfeel.
- Flour
- Starch that thickens the milk into a sauce as it heats.
- Bread
- Absorbs the sauce, becoming soft and moist while keeping some body.
The step that matters
Boil the milk with the butter and flour. Flour starch only thickens fully when heated with liquid, so the mixture needs to be brought to a boil and stirred. Stirring keeps the flour dispersed so it does not form lumps.
