Why it works: Milk and egg 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 ↓
Cold Custard
Ingredients
Directions
Prepare the milk
Wet a saucepan with cold water to prevent burning.
Pour out the water and add 1 quart of milk; boil and let it cool slightly.
Make the custard
Beat the yolks of 6 eggs, then mix in 3 ounces of sugar and ¼ teaspoon of salt.
Add the lukewarm milk to the egg mixture and stir well.
Pour the mixture into a double saucepan and stir over heat until it thickens to a cream‑like consistency.
Strain the custard and let it cool almost completely before adding flavoring if desired.
Chill and serve
Pour the custard into cups and place them on ice until ready to serve, or freeze in a freezer.

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
- Egg yolks
- Thicken the custard as they set with gentle heat, giving it a smooth, rich body.
- Milk
- Forms the main liquid base that the egg yolks thicken into a custard.
- Sugar
- Sweetens the custard and helps keep its texture smooth as it sets.
The step that matters
Stir the custard over heat until it thickens. Egg yolks begin to set around 160°F, so gentle heat and constant stirring are needed. Overheating can curdle the eggs, leaving a grainy texture instead of a smooth cream-like custard.
