Why it works: Egg and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 88,785 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the custard as their proteins set during gentle heating, giving it body.
- Milk
- Forms the liquid base that the eggs thicken into a smooth custard.
- Sugar
- Adds sweetness and helps the beaten eggs stay smooth.
The step that matters
Adding the hot milk to the eggs. If hot milk is poured in too fast or without stirring, the egg proteins set in lumps and the custard curdles. Pouring slowly while stirring constantly gently warms the eggs so they blend smoothly before the mixture returns to the saucepan.
