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
- Eggs
- Their proteins set when gently heated, thickening the custard.
- Milk
- Forms the liquid base that the eggs thicken into a smooth custard.
- Sugar
- Adds sweetness to the custard.
The step that matters
Cook on low heat and do not let the custard boil. Egg proteins thicken gently when heated slowly. Too much heat makes them tighten and curdle, leaving the custard grainy instead of smooth.
