Milk and sugar 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
- Milk
- Forms the liquid base of the custard that the yolks thicken.
- Egg yolks
- Their proteins set when gently heated, thickening the milk into a custard.
- Sugar
- Adds sweetness to the custard.
- Egg whites
- Whipped into a foam whose trapped air gives the light, airy islands their structure.
The step that matters
Thickening the custard over heat. Egg yolk proteins set gently at moderate heat. If the milk and yolks get too hot or heat too fast, the yolks scramble and curdle, leaving a grainy custard instead of a smooth, thick one.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
