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

Ingredients
Directions
Prepare
Beat eggs quickly and sharply, separating whites and yolks, using stone or earthenware, not tin.
Boil milk in a custard kettle made of iron with an inner iron kettle.
For custard, combine 4 eggs, 1 cup sugar, 1 salt‑spoon salt per quart milk.
Beat yolks and whites separately; add the whites last.
Optionally strain the beaten yolks through a small wire strainer.
Set the custard
If using gelatin, soak it for 1–2 hours in cold water or milk, then set in a warm place (e.g., a bowl on top of a boiling kettle) until dissolved.
When gelatin is dissolved, pour it into the hot custard immediately after removing from the stove.
Bake in a baking dish or cup set in a pan of hot water until firm in the center, using moderate heat to avoid curdling.
For a more elegant custard, whip the whites and place them over the top when hot.

Sugar and milk share little aroma chemistry, yet 77,875 recipes mention both: they likely 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
- Coagulate on heating to set the custard into a firm, tender structure.
- Sugar
- Adds sweetness and softens the set custard's texture.
- Milk
- Provides the liquid base that the eggs thicken into custard.
- Gelatin (in the method)
- Adds extra setting strength so the custard holds its shape.
The step that matters
Bake over moderate heat in a water bath. Egg proteins set gently at moderate temperatures. Too much heat makes them tighten and curdle, leaving the custard grainy and watery instead of smooth.
